Find the remainder after division by a negative divisor for a set of integers including both positive and negative values. Consider a unit chirp embedded in white Gaussian noise and sampled at 1 kHz for 1.2 seconds.Remainder After Division for Negative Divisor. The function bandpower allows you to estimate signal power in one step. So we have The power of a signal is the sum of the absolute squares of its time-domain samples divided by the signal length, or, equivalently, the square of its RMS level. For example, if we consider the multiplicative group of integers modulo 12, then 7 has an inverse, since it is co-prime with 12. Even when the modulus is composite, you need the modulus to be co-prime to the value in question for a modular inverse to exist.When you specify a scalar value to be divided by an array, the scalar value expands into an array of the same size, then element-by-element division is performed. Create an array and divide it into a scalar. The input parameters are vector of integers X and a scalar P which represents the field order. if Y = MULINV (X,P) then (X*Y) mod P = 1 or Y = X^ (-1) over field of order P. Discussions (0) MULINV (X,P) is a function that finds the modular inverse of vector X over finite (Galois) field of order P, i.e.%%% MATLAB codeclcclear allclose all = fop.

Let us now understand how to use the mod function in MATLAB. R = mod (X, Y) is used to return the remainder when the Dividend ‘X’ is divided by the Divisor ‘Y’.
