percentage

I am currently using the built in random number generator.

for example

nAsp = randi([512, 768],[1,1]);

512 is the lower bound and 768 is the upper bound, the random number generator chooses a number from between these two values.

What I want is to have two ranges for nAsp but I want one of them to get called 25% of the time and the other 75% of the time. Then gets plugged into he equation. Does anyone have any ideas how to do this or if there is a built in function in matlab already?

for example

nAsp = randi([512, 768],[1,1]); gets called 25% of the time

nAsp = randi([690, 720],[1,1]); gets called 75% of the time
