Function Documentation

verify()

function verify	(	in	varval,
		in	vartype,
		in	varsize,
		in	varname
	)

Verify the type and number of elements of the input varval match the specified input vartype and varsize.
Otherwise, halt the program by calling the MATLAB intrinsic error() with an appropriate descriptive error message.

This function is merely a higher-level wrapper around the ParaMonte functionality pm.introspection.istype().
The goal is to offer a unified interface for argument verification and aborting the program with a suitable error message if the verification fails.

Parameters

[in]	varval	: The input value to whose type and number of elements is to be verified.
[in]	vartype	: See the documentation of the corresponding argument of pm.introspection.istype().
[in]	varsize	: See the documentation of the corresponding argument of pm.introspection.istype().
[in]	varname	: The input scalar MATLAB string containing the label to assign to the namelist-converted value in the output entry. The specified value of varname will be trimmed (to remove leading and trailing blanks) and used only for outputting an error message. (optional, default = "value")

Possible calling interfaces ⛓

pm.introspection.verify(varval, vartype, varsize);
pm.introspection.verify(varval, vartype, varsize, varname);

Example usage ⛓

cd(fileparts(mfilename('fullpath'))); % Change working directory to source code directory.
addpath('../../../'); % Add the ParaMonte library root directory to the search path.
 
pm.introspection.verify(10000, "integer", 1, "varname");
pm.introspection.verify(10000, "integer", 1);
pm.introspection.verify("text", "string", 1);
pm.introspection.verify('text', "char", 4);
pm.introspection.verify('text', "char", 5);
pm.introspection.verify(1, "complex", 1);
pm.introspection.verify(1, "real", 1);
pm.introspection.verify(int32(1), "int32", 1);
 
try
    pm.introspection.verify(10000, "string", 1);
catch me
    warning(string(me.identifier) + string(me.message));
end

Example output ⛓

value = 
       10000
