MATLAB: How can i generate a random number between two float numbers

Question

I am trying to generate a random number between two float numbers by using

    val = randi([mnval mxval],1,1)
where mxval and mnval are two float numbers. when i run the above command "First input must be a positive scalar integer value IMAX, or two integer values [IMIN IMAX] with IMIN less than or equal to IMAX." error is coming.

Answer 1

This is one of the examples in the rand doc:

val = mnval + rand*(mxval-mnval);
