imread MATLAB script gives error 1048

[Cyclothymia]

I have been struggling to get imread to work in MATLAB scripts. I have gotten the exact same lines of code to work both in the MATLAB Command Window from LabVIEW, and in MATLAB as well. I believe my variables (only one to output the resultant image array) have been named correctly.

I have considered using Mathscript also (imread works in Mathscript with some modification to data types), but if imread works, I will need to call the GRAB function which uses cell arrays. Although I could have modified the code to avoid using cell arrays it would be a last resort.

When running the vi I get the following error:

========================================================================

Error 1048 occurred at LabVIEW: LabVIEW failed to get variable from the script server. Server:"7.4.0.287 (R2007a)

" in MATLABscripts.vi

Possible reason(s):

LabVIEW: LabVIEW failed to get variable from the script server.

========================================================================

I have looked up on knowledgebase information on the NI website, and also [HERE], to no avail.

The version of LabVIEW I am using is 8.5, and for MATLAB 2007a. Any help would be appreciated.

UPDATE: SOLVED

I realized that this was due to a typecasting problem:

MATLAB on its own has smart casting during function calls.

When running the script in LABVIEW, which is strictly typed,

the solution was to explicitly cast imread into double():

bar = double(imread("foo.jpg"));
