Return
Save for Previous on a VI with MathScript results in broken VI
If you select File»Save for Previous Version and save a VI that contains a MathScript Node for LabVIEW 8.0, the VI is broken when you load it in LabVIEW 8.0.

Workaround: To correct this problem, load the VI in LabVIEW 8.0 and then modify the script in the MathScript Node. For example, add and remove a space. Then click the block diagram outside of the MathScript Node. When you click the Run button, the VI runs correctly.

Reported Version: 8.5    Resolved Version: N/A    Added: 09/01/2007
114532

Return
MathScript cannot create a subplot with multiple 3D graphs on it
MathScript always creates a new plot window for 3D graphs, such as surf and mesh.

Workaround: N/A

Reported Version: 8.6    Resolved Version: N/A    Added: 08/01/2008
99061

Return
MathScript Probe on a reentrant clone attaches to the original
If you try to probe a MathScript node on a clone of a reentrant VI, the probe will actually attach to the original VI instead.

Workaround: Turn off reentrant execution on the VI that contains the MathScript node before you attach the MathScript probe.

Reported Version: 8.6    Resolved Version: N/A    Added: 08/01/2008
194964

Return
RT Target may crash when closing the block diagram of a running VI with the MathScript Probe
If you are running a VI on a Real-Time target with a MathScript Probe attached to a MathScript node, closing the block diagram may cause the target to crash.

Workaround: Close the MathScript Probe before closing the block diagram.

Reported Version: 2009 SP1    Resolved Version: N/A    Added: 06/17/2010
195525

Return
MathScript search path incorrectly shows one of the paths to be invalid
When the project is moved, one of the paths in the search path wrongly shows up as invalid.

Workaround: After saving the project, open the search path page and click ok.

Reported Version: 2009    Resolved Version: N/A    Added: 06/17/2010
174668

Return
Removing inner function in .m file breaks VI
When a referenced .m file contains two functions, one of which calls the other, removing the bottom function (and changing the top function to not depend on it) breaks the caller VI.

Workaround: This is just an extraneous error appearing in the error list window. If all the other errors in the caller VI are fixed, the VI becomes good.

232284

Return
Attaching a probe to large MathScript Node while running on RT can cause connection loss
If a large MathScript Node is running on a RT target and you try to attach a probe, you occasionally lose connection to the target. If you then reconnect, the probe will work normally.

Workaround: N/A

Reported Version: 2009 SP1    Resolved Version: N/A    Added: 06/20/2011
234580

Return
Running 'clc' clears the output of some commands executed after calling it
If 'clc' is used, it should clear the output window then run the script that follows it. The output window should populate with the output of the rest of the script. Instead, 'clc' ' clearis the output of some of the later commands in the same script.

Workaround: N/A

Reported Version: 2010    Resolved Version: N/A    Added: 07/21/2011
127425

Return
Filled Contour Plot does not recognize hold command
When using a filled contour plot, one cannot then "hold" the plot in order to plot more on top of it. Plotting additional data will clear the plot.

Workaround: N/A

Reported Version: 8.6    Resolved Version: N/A    Added: 07/18/2012
138460

Return
Title function does not work with 3D plot
The title function has no effect on a 3D plot.

Workaround: N/A

Reported Version: 8.6    Resolved Version: N/A    Added: 07/18/2012
187387

Return
MathScript Probe can become unresponsive
When probing a MathScript node that writes to large matrices repeatedly the probe can become unresponsive.

Workaround: N/A

Reported Version: 2009 SP1    Resolved Version: N/A    Added: 07/18/2012
223370

Return
Opening a VI with a MathScript node on a machine with invalid MathScript license may cause a error dialog box to show up
When you open a VI with a MathScript node on a machine that does not have valid MathScript license, you may see a error dialog pop up reporting an 'insanity' error.

Workaround: It is cosmetic error and can be safely ignored

Reported Version: 2010    Resolved Version: N/A    Added: 07/18/2012
290936

Return
The fread function returns variant data type even when type is specified
The fread function returns variant data even when the parameter specifying the type of data you are reading is used.

Workaround: Use data type conversion after the function to cast to the appropriate type.

Reported Version: 2010    Resolved Version: N/A    Added: 07/18/2012
358651

Return
MathScript Examples are in English in localized version of LabVIEW
The MathScript examples appear in English even in a localized version of LabVIEW.

Workaround: N/A

Reported Version: 2012    Resolved Version: N/A    Added: 07/18/2012
359717

Return
Using LabVIEW 2012 MathScript RT Module may cause issues when subsequently using LabVIEW 2011 MathScript RT Module
You may get an error "-90086 LabVIEW cannot compile the current MathScript. Contact National Instruments with the MathScript you used." when calling an m-file in LabVIEW 2011 if you have previously called that m-file in LabVIEW 2012.

Workaround: Delete "LabVIEW Data\MathScriptVIs" after closing LabVIEW 2012 and before launching LabVIEW 2011.
