#probability to generate samples of random variable
➡️ #scilab use grand() and specify the the low and parameters "def" for uniform in [0,1], "nor" for normal ... 👍
➡️ #gnuoctave use rand() for uniform in [0,1], randn() for norma N(0,1) rande() for exponential with parameter 1 , randp() for Poisson ...😐
➡️ #matlab use rand() or randn() or exprand() or ... nothing 🤦♂️
