Sign in to answer this question. For example, if Sample time and Samples per frame equal one, the block outputs a sample every second. The rand function returns real numbers between 0 and 1 that are drawn from a uniform distribution in MATLAB. One method is to use randperm so that you generate a random permutation of n values that are enumerated from 1 up to and including n, and only return the first two elements of the result:. Vote. To get normally distributed random numbers with mean and standard deviation other than the standard normal distribution ($\mu=0,\sigma=1$), you will have to use another MATLAB builtin function normrnd(),. Each number from 1 to n should appear only once. https://de.mathworks.com/matlabcentral/answers/58454-how-to-generate-random-integer-number-in-a-fixed-range-in-matlab-like-between-1-to-10#comment_764831, https://de.mathworks.com/matlabcentral/answers/58454-how-to-generate-random-integer-number-in-a-fixed-range-in-matlab-like-between-1-to-10#answer_70731, https://de.mathworks.com/matlabcentral/answers/58454-how-to-generate-random-integer-number-in-a-fixed-range-in-matlab-like-between-1-to-10#answer_70735, https://de.mathworks.com/matlabcentral/answers/58454-how-to-generate-random-integer-number-in-a-fixed-range-in-matlab-like-between-1-to-10#comment_692155, https://de.mathworks.com/matlabcentral/answers/58454-how-to-generate-random-integer-number-in-a-fixed-range-in-matlab-like-between-1-to-10#comment_721802, https://de.mathworks.com/matlabcentral/answers/58454-how-to-generate-random-integer-number-in-a-fixed-range-in-matlab-like-between-1-to-10#comment_1092108, https://de.mathworks.com/matlabcentral/answers/58454-how-to-generate-random-integer-number-in-a-fixed-range-in-matlab-like-between-1-to-10#answer_393572.
