I thank if some one can help in this, how can i generate a matrix of some size for ex 100x100 with in the range of [-0.01,0] and that too with decimal values contained in it like -0.001,-0.0056 like that and also for the ranges like [-60,-30] with decimal values like -58.254,-56.985 and only 3 decimal values after the point.

This is a learning task, or what?

The answer to this is the example to rand() in the help.

Sorry but you are wrong. Look at Greg's code below, which is the same as the help example I referred you to. You can certainly have "a" and "b" be negative numbers. Why do you think you can't? No one said they had to be positive.

n=3; %number of decimal places
A = randi([-60,-30]*10^n,[100,100])/10^n;

x = a + (b-a)*rand(m,n);
Hope this helps.
