function varargout = sdspwfall(varargin) %SDSPWFALL DSP System Toolbox Level 2 MATLAB file S-function %implementing waterfall plot. % Copyright 1995-2020 The MathWorks, Inc. % The following block callbacks are assumed % to be set in the library block: % ----------------------------------------- % CopyFcn "sdspwfall([],[],[],'BlockCopy');" % DeleteFcn "sdspwfall([],[],[],'BlockDelete');" % UndoDeleteFcn "sdspwfall([],[],[],'BlockUndoDelete'); % LoadFcn "sdspwfall([],[],[],'BlockLoad');" % ModelCloseFcn % PreSaveFcn % PostSaveFcn % InitFcn (done via S-fcn) % StartFcn (done via S-fcn) % StopFcn (done via S-fcn) % NameChangeFcn "sdspwfall([],[],[],'BlockNameChange');" % ClipboardFcn % DestroyFcn unused: fires when block no longer able to be % un-deleted, generally at model close % OpenFcn "sdspwfall([],[],[],'BlockOpen'); % CloseFcn % ParentCloseFcn % MoveFcn % DeleteChildFcn % ErrorFcn "sdspwfall" % MaskInitialization "sdspwfall([],[],[],'DialogApply');" % % Load-time sequence of calls % --------------------------- % Note that MaskSelfModifiable is turned on for this library block, % in order to get the mask parameters evaluated during load-phase % of a model that contains the block. This is necessary so we know % whether the block must be opened, parameters affecting the initial % scope placement, etc. % % Block Event Handle ParamsEvaluated % ----- ----- ------ --------------- % <Load time of model and library> % library LoadFcn x no % model InitFcn y1 yes (we ignore this event) % model LoadFcn y2 yes (first event we react to) % % <Update diagram: ctrl+d) % model Dynamic y2 yes (mask dialog) % model InitFcn y2 yes % % Note that due to the MaskSelfModifiable load sequence, the block % handle during the first InitFcn prior to LoadFcn is not the same % as the block handle during the rest of the load sequence. % % Note that when a block is deleted, and then un-deleted, % the LoadFcn does not execute again. Instead, we set the % UndoDelete function and have it go to the LoadFcn callback. % % Note: leave userdata on the subsystem, and don't move it % to the underlying s-function block. We can guarantee a % change in handle for that case, so that will be pointless. % The parent/subsystem should have a constant handle, despite % the current bug. % % What's in the Figure userdata: % ------------------------------ % Main scope figure handles: % fig_data.block block name % .hfig handle to figure % .haxis handle to axes % .history.slider % .history.labels % .history.frame % .hStatusBar.Region % .hStatusBar.StatusText % .hStatusBar.DataSizes % .hStatusBar.TraceInfo % .hStatusBar.XformMode % .hStatusBar.All all except .Region and .StatusText % % Handles to menu items: % fig_data.menu.sptool export to SPTool % .axisgrid (checkable) % .snapshot (checkable) % .suspend (checkable) % .autoscale % .top top-level Axes and Lines in Figure % .context context menu % .icons for dynamic icons % .buttons button bar % .buttons.Toolbar % .buttons.Params % .buttons.[lots more!] % % What's in the Block userdata: % ----------------------------- % block_data.hfig handle to figure % .haxis handle to axes % .hsurf surface handle % .hdiscontig handle to discontiguous-time indicator lines % .params structure of cached block dialog parameters % .bdroot % .BufferFullFcn what to do when history buffer fills % .InputPortDims block input dimensions % .IsScalarInput derived from .InputPortDims % .indims dimensions into history service % (eg, dimensions coming out of data transformation) % .HistoryLengthActual % .HistoryID % .HistoryRecFcn % .HistoryRecFcn_suspend % .TriggerFcn % .TriggerData % .UserFcn % .LastTimeStamp % .Cnt input count for trigger % .UpdateFcn % .XformFcn user-defined data transformation function % .UpdateIntervalCounter display-update interval counter % .DiscontigColors % .LastTimeStamp % .LastDiscontigSet % .Ts % .ScopeToolbarVis Scope toolbar visibility, 'on' or 'off' % .param_dlg.hfig % .param_dlg.pos % .param_dlg.tabNum % % Parameters structure fields: % ---------------------------- % params.NumTraces scalar, # of traces % .CMapStr colormap fcn name (string) % .TNewest Transparency fraction, 0=opaque, 1=transparent % .TOldest % .HistoryLength edit box, # inputs (beyond one displayfull) % to record in history buffer % Overwrite, Suspend: actual buffer size % Extend: initial buffer size % .HistoryFull Popup (Overwrite, Suspend, Extend) % .UpdateInterval edit, # inputs to record before updating display % .MouseMode Popup, literal: Arrow|Orbit|Zoom % .AxisGrid Checkbox % .Snapshot Checkbox % .Suspend Checkbox % .SyncSnapshots Checkbox % .OpenScopeAtSimStart checkbox % .FigPos figure position % .CameraView edit box with vector % .InportDimsHint edit box with dimensions vector % .YMin: Minimum input data value % .YMax: Maximum input data value % .XLabel: x-axis label for main image % .YLabel: y-axis label for main image % .ZLabel: color bar scaling label % % .TrigStartMode: popup, literal % 'Immediately|After T seconds|After N inputs|User-defined' % .TrigStartT edit box, eval % .TrigStartN edit box, eval % .TrigStartFcn edit box, literal % .TrigStopMode popup, literal % 'Never|After T seconds|After N inputs|User-defined' % .TrigStopT edit box, eval % .TrigStopN edit box, eval % .TrigStopFcn edit box, literal % .TrigRearmMode popup, literal % 'Never|After T seconds|After N inputs|User-defined' % .TrigRearmT edit box, eval % .TrigRearmN edit box, eval % .TrigRearmFcn edit box, literal % .XformMode popup, data transformation mode % .XformExpr edit, literal, expression % .XformFcn edit, literal, function name % % HistorySvc % ---------- % History is stored as individual records (structures) % rec.Values % .Time % .Discontig % Gecks: % ----------------------------- % PRIORITY 1 % (-- these next few are related --) % ENH: scalar inputs, improve message % ENH: if block is disconnected, what to display? % CheckInportAttributes % probably some informative text instead of a display % consider suspend mode if disconnected % (be sure to disregard sync flag, however) % ENH: (follow up to disconnected block msgs) % -> want some sort of general message display for error conditions. % Blank axis, centered message - no "hard errors" % Use for invalid input data as well % (-- these next few are related --) % ENH: unify input/xform data handling % - w
