randi

Random Integer.

📝 Syntax

• X = randi(imax)

• X = randi(imax, n)

• X = randi(imax, sz)

• X = randi(imax, ..., typename)

• X = randi(imax, ..., 'like', p)

• X = randi([imin, imax], ...)

📥 Input argument

• imax - Maximum integer value (inclusive).

• imin - Minimum integer value (inclusive).

• n - Generates an n-by-n matrix.

• sz - Size vector specifying the size of the output array.

• typename - Data type of output: "single", "double", "int8", "uint8", "int16", "uint16", "int32", "uint32", or "logical".

• p - Array whose type and complexity are used for output.

📤 Output argument

• X - Array of random integers.

📄 Description

randi returns random integers drawn from a discrete uniform distribution.

X = randi(imax) returns a random scalar integer between 1 and imax.

X = randi(imax, n) returns an n-by-n matrix of random integers between 1 and imax.

X = randi(imax, sz) returns an array where size vector sz defines size(X).

X = randi(imax, ..., typename) returns an array of random integers of type typename.

X = randi(imax, ..., 'like', p) returns an array of random integers like p (same type and complexity).

X = randi([imin, imax], ...) returns random integers between imin and imax.

💡 Examples

X = randi(10)

X = randi(10, 3, 4)

X = randi(10, [3 4])

X = randi(10, 3, 4, 'int32')

p = single([3 3]);
X = randi(10, 3, 3, 'like', p)

X = randi([5, 15], 2, 3)
