how to generate different sequence everytime using randsrc

i tried to created a 48X1 array of randomized M and Z and need to run it for 4 times (each generate a different randomised M and Z sequence )

i have used :

a = randsrc(1,48, [77 90 ; 0.45 0.55],48)

b=char(a)

but all of the sequence i have got are the same. i dont know wheere i went wrong . can anyone shed some light on this .

thanks .

This is expected since the function is seeded with a value.

randsrc(m,n,___,seed)

If you remove the seed, the function will assume a random seed each time it is run.
