This function is used to seed the uniformly distributed random number generator (RNG). It must be called prior to using any of the 32-bit RNG's provided in DSPLIB
seed | = An arbitrary unsigned integer chosen by the user. | |
polynomial | = Array of 3 non-arbitrary unsigned integers, previously generated using the included TinyMTDC program and/or from the provided text file; numbers from different sets MUST NOT be mixed and matched. Should the user provide a NULL pointer instead, default values will be used instead. These parameters ensure (mostly) statistically independent random numbers among different generators. Users should place numbers in the polynomial parameter in the order in which they appear in the text file or TinyMTDC program. That is columns 0, 1, and 2 (mat1, mat2, and tmat of TinyMTDC) correspond to positions 0, 1, and 2 of the polynomial. | |
state | = An array of 7 unsigned 32-bit integers which need not be initialized to any values by the user; the user is only required to allocate such space and maintain (but NEVER modify) it. |
