Is there a Matlab function to convert any data structure to a string?

Question

I\'m looking for a function in Matlab to use for error messages, like so:

error([\'Invalid value for someVariable: \' wantedFunction(someVariable)]);
         


        

Answer 1

Looks weird, but

str = matlab.unittest.diagnostics.ConstraintDiagnostic.getDisplayableString(value)

does the job for you instead using that unesthetic evalc(disp()) approach.
