random number generation function in matlab
Jan 05th, 2012, 4:17am
 
i wanted to use normrnd(mu,sigma,m,n) in ordetr to generate random numbers from normal distribution with mean mu =0 and some standard deviation say sigma. But my matlab doesnt support statistical toolbox.

Another possibilty i look is to use randn(m,n) which has mean =0 and standard deviation equal to 1 and this is normal matlab functionality.

Please tell me how i can use randn function with some standard devation value = sigma (say) instead of 1??

thanks in advance

Multiply by sigma (see example 1 from http://www.mathworks.com/help/techdoc/ref/randn.html).
