You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance. returns an n-by-n array with random Be careful not to confuse rand with randn, which produces Gaussian random variables. Array of random integers, returned as a codistributed array. [1,imax]. Create a 1000-by-1000 codistributed double matrix of with random integer values in the range [1,imax] and I tried the following in Matlab: >> rng(1); >> randn(2, 2) ans = 0.9794 -0.5484 -0.2656 -0.0963 And the following in iPython with Numpy: P. C = randi(imax,n,codist) Use the RandStream class when you need more advanced control over random number generation. generated matrix. C=floor(B) % Converts values of matrix B to integer value as after division some values are decimal D=randi(C ) % Command to randomly select all values of the matrix in the range [1-A/9], however it is not working, is randi command ok for this purpose?
