matlab randi

randi is a function in MATLAB that generates random integers based on various parameters specified by the user.

Syntax:

randi(imax) generates a random integer between 1 and imax.

randi([imin imax]) generates a random integer between imin and imax.

randi(imax, sz) generates a sz-by-sz matrix of random integers between 1 and imax.

randi([imin imax], sz) generates a sz-by-sz matrix of random integers between imin and imax.

randi(imax, sz1, sz2, ...) generates an array of sz1-by-sz2-by-... random integers between 1 and imax.

randi([imin imax], sz1, sz2, ...) generates an array of sz1-by-sz2-by-... random integers between imin and imax.

Example:

To generate a random integer between 1 and 10:

randi(10)

To generate a 3-by-3 matrix of random integers between 1 and 5:

randi(5, 3)

To generate a 2-by-2-by-2 array of random integers between 10 and 20:

randi([10 20], 2, 2, 2)
