INT32 INT32 Convert to Signed 32-bit Integer Usage Converts the argument to an signed 32-bit Integer. The syntax for its use is y = int32(x) where x is an n-dimensional numerical array. Conversion follows the general C rules (e.g., if x is outside the normal range for a signed 32-bit integer of [-2147483648,2147483647], the least significant 32 bits of x are used after conversion to a signed integer). Note that both NaN and Inf both map to 0.
