A matrix of know dimensions and random values can be created by using the rand() function. You just need to provide the required dimension of row and column in the the rand() function. As per your example, you can create your matrix by rand(5,3)
You can leverage the Matlab documentation of the rand() function , you can also find out related functions in the link below :

For random numbers uniformly distributed on [0,1] :
A = rand(5,3);
