RandIntegers

Selects random integers between and inclusive of specified lower and upper limits.

You are now following this Submission

RANDINTEGERS(LOWER_BOUND,UPPER_BOUND) is a one line function that uses RAND to return a random integer between and inclusive of the two specified integers LOWER_BOUND and UPPER_BOUND (with uniform probability) (and with replacement).

The third argument M_SIZE is optional. If specified as a scalar, the output is a matrix with size [m_size m_size] and containing the values stated above. If specified as a row vector, the output is an array with size [m_size] and containing the same.

Examples:

randinteger(11,25) may return 23 or 25 or 11
randinteger(11,25,2) may return [25 12; 15 24]
randinteger(11,25,[1 3]) may return [14 23 17]

Remarks:

As depicted in the help text within the function, the Communications and Statistics toolboxes each contain a function that can be used for the same purpose.
