Assigning Numeric Range to MATLAB Symbols

I have constant symbols such as 

t = sym('t')
c = sym ('c')

but I have to restrict these symbols with a constraint stating that t is between 0 and 1 (greater equal to zero, smaller equal to one). For c just greater and equal to zero.

I can easily assign a number in matlab by just denoting 

t = 0;

but I need help to put these symbols in an interval.

Solution 
  • assume(t > 0);
assumeAlso(t < 1);

    Then, you can decide things like

    isAlways(t^2 < 1)

    For the > 0 part, you can use the abbreviation

    c = sym('c', 'positive')
