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.

@ Image Analyst no rand did not work for negative numbers.

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.
