Expected FunctionSignatures to be a non-missing string scalar or character vector.

Hello. I am getting the following error and cannot solve it:

Expected FunctionSignatures to be a non-missing string scalar or character vector.

Which is produced from running the following:

compiler.build.productionServerArchive(templates, ArchiveName=archive_name, FunctionSignatures=function_signatures);

Where templates is:

{'C:\Users\cgreff\AppData\Local\Temp\matlab\st…'}    {'C:\Users\cgreff\AppData\Local\Temp\matlab\st…'}    {'C:\Users\cgreff\AppData\Local\Temp\matlab\fe…'}

And where function_signatures is:

{'C:\Users\cgreff\AppData\Local\Temp\matlab\st…'}    {'C:\Users\cgreff\AppData\Local\Temp\matlab\st…'}    {'C:\Users\cgreff\AppData\Local\Temp\matlab\fe…'}

Any help would be greatly appreciated

Hi Chandler,

"productionServerArchive" function expects FunctionSignatures parameter to be character vector or string scalar. Here is the syntax to add FunctionSignatures parameter:

'FunctionSignatures','<path>\<filename>.json' % Path to a single json file is accepted

Refer to the following MathWorks documentation for more information on:
