Read Matlab (1024 x 768) matrix (type=double) into mathscript node

[TimEatUT]

I am having extreme difficulty trying to perform a very simple operation. I need to read in a 1024x768 Matrix (type double) called "a1" from Matlab using the mathscript node and then output a1 from the node and display it as a matrix in Labview. The matrix file is save as 'C:\users\Tim\VIs\a1.mat'. This should be a very simple operation, but I cannot get Labview to read in the matrix properly. You're help is greatly appreciate. Here is a copy of the VI and a copy of the matrix file I am trying to read in.

The Mathscript node isn't the same as Matlab. Mathscript is NI's version of a Matlab-like scripting language. The load function in Mathscript is limited to reading .mat files that have written using Matlab version 6 or earlier. This is detailed in the Help. What version of Matlab did you use? If you have a newer version of Matlab then you can save the data in another format, such as simple text. Then you can use the simple File I/O functions to read it into LabVIEW. There may be also be a .mat file reader floating around. I know I wrote one a while ago (and had posted it), but it was for an older version of the .mat file format.
