Function	What it does
disp	Display the value of a variable without printing its name.
iscomplex	Element-wise complex-type test.
isempty	Test whether the input has zero elements.
isequal	Test whether two or more inputs are equal in shape and value.
isequalwithequalnans	Like isequal, but treats NaNs as equal to other NaNs.
isfinite	Element-wise finite test.
isinf	Element-wise infinity test.
isinteger	Test whether the input is integer-typed (or, in script mode, integer-valued).
isintegral	Element-wise integer-value test.
islogical	Test whether the input is of logical (boolean) type.

isscalar	Test whether the input is a 1×1 scalar.
isvalid	Element-wise validity test.
isvector	Test whether the input is a vector (one row or one column).
iszero	Element-wise zero test.
length	Length of the longest dimension.
max	Maximum value along a dimension, or elementwise maximum of two inputs.
min	Minimum value along a dimension, or elementwise minimum of two inputs.
ndims	Number of dimensions of the input.
numel	Total number of elements.
size	Sizes along all dimensions, or along one specific dimension.
size_equal	Test whether all inputs share the same shape.
sizeof	Storage size of the input in bytes.
