Determine if mxArray
represents data as double-precision, floating-point numbers
C Syntax
Arguments
array_ptr
Pointer to an mxArray
.
Returns
Logical 1
(true
) if the mxArray
stores its data as double-precision, floating-point numbers, and logical 0
(false
) otherwise.
Description
Call mxIsDouble
to determine whether or not the specified mxArray
represents its real and imaginary data as double-precision, floating-point numbers.
Older versions of MATLAB store all mxArray
data as double-precision, floating-point numbers. However, starting with MATLAB version 5, MATLAB can store real and imaginary data in a variety of numerical formats.
Calling mxIsDouble
is equivalent to calling
