Cast variable to different data type


B = cast(A,newclass)
B = cast(A,'like',p)


B = cast(A,newclass) converts A to class newclass, where newclass is the name of a built-in data type compatible with A. The cast function truncates any values in A that are too large to map into newclass.

B = cast(A,'like',p) converts A to the same data type and sparsity as the variable p. If A and p are both real, then B is also real. Otherwise, B is complex.
