How can I generate a matrix of pseudo-random floating point values from a uniform distribution(5, 8), but without range() function and other ToolBoxes?
matrix = rrange(1) + range( rrange ) * rand( 5, 8 ) % now I have this variant,
% it works, but I cannot use ToolBoxes

Does this mean, that you cannot use rand()?
range() is trivial to replace: rrange(2)-rrange(1)

Oh, thank you. Frankly, I meant range(), bud I did not know what does it do)

In general, if you're not sure what a function does or which MathWorks product includes it, take a look at the documentation for that function. In particular, if you look at the rand function's documentation the "Random Numbers Within Specified Interval" example exactly matches what you're trying to do.
If you're using the range function from Statistics and Machine Learning Toolbox, for a general vector calling the bounds function in MATLAB with two output arguments and subtracting the first output from the second does the same thing as range. For a 2-element vector in increasing order this simplifies to the replacement @Jan posted.
