How to set assumptions in matlab

  1. Aug 14, 2011 #1
    1. The problem statement, all variables and given/known data

    I want to know how to set assumptions in Matlab. i want to integrate 3*a*x/b but i want to tell matlab that b is less than a.

    2. Relevant equations

    3. The attempt at a solution

    I know how to set assumptions that a variable is real/nonreal/positive/negative.
    eg: sym('a','positive')
    but not specific assumptions as b<a.

    Thank you in advance.
