0—namedoes not exist or cannot be found for other reasons. For example, ifnameexists in a restricted folder to which MATLAB does not have access,existreturns 0. 1—nameis a variable in the workspace. 2—nameis a file with extension.m,.mlx, or.mlapp, ornameis the name of a file ...
When you start MATLAB usingmatlab-proxy, MATLAB will first run astartup.mfile, if one exists on your path. For details, seeUser-defined startup script for MATLAB. MATLAB will then run any code you have provided as a string to theMWI_MATLAB_STARTUP_SCRIPTenvironment variable. ...

This assigns the string Male to variable. For large amounts of data, perhaps saved in a previous Matlab session, the function load allows the loading of files from disk using load filename The filename normally ends in .mat or .dat. A file of sunspot data already exists in the Matlab...
2. I did change the variable name but still, I see the following message every time I build the model. I am still getting 0V on CellVoltage. Is there a way to check if there is a communication error? Thanks rparveez 07-21-202001:33 PM ...
If a variable already exists in a MAT-file, then save overwrites it with the value in the workspace. For ASCII files, "-append" adds data to the end of the file. To append to a Version 6 MAT-file, you must also specify version as "-v6"....
