Function Documentation

void DSPF_sp_urand	(	unsigned int	size,
		float *	vector,
		void *	state
	)

This function is used to fill an array with uniformly distributed random floats on the interval [0, 1).

Parameters:

	size	= The size of the array to be filled.
	vector	= The array of type float which the user wants to fill with random values.
	state	= The array which was initialized with the "DSP_urand32_init" function and maintained (but NEVER modified) by the user between subsequent calls to this function.

Algorithm:

The random number generator is based on "DSP_urand32." Random integers are generated in the same manner and then multiplied by 1/(2^32) (rounded to to 2.3283064e-010 for single-precision arithmetic) and then cast to float to ensure a proper range of [0,1).

Assumptions:

The user has previously called the "DSP_urand32_init" function at least once, has maintained the state array, and allocated an array of float types of the desired width.

Implementation notes:

Endian Support: The code supports both big and little endian modes.
Interruptibility: The code is not interruptible.
