Returns a matrix of random elements drawn uniformly from within a specified set. Sampling can be done with or without replacement. (This function was intended to fill the role of RANDINT in the Comm Toolbox, which I no longer possess. No claims are made for correctness or efficiency.)
Program does not work well when randomly generating numbers when drawn without replacement. This can be observed by using the program to randomly obtain values within a range. Sort the results and plot using a histogram. It appears that the limits in and the middle value of the range are preferentially treated.
for n = 1:10000
p(n,:) = myrandint(1,3,[1:23],'noreplace');
why don't you just use something like
This will generate an nxm matrix with randomly chosen integers from 1 to t.

This is a simple but nicely crafted replacement for the randint() function. The only drawback that I can see if that rand(), which generates random double-precision floats, it being used to generate random integers. It should be possible to generate random integers without doing floating point operations.

It is an excellent function can used to generate random problems for linear programming.

very good, works fine, if you don't know that it is missing from the standard libraries you may seach for hours in the Help files

I removed the silly FOR loop.

Removed a bug that returned vectors of the wrong orientation.
