May 09, 2020 · A ‘1 x 1 sym’ is a single scalar symbolic expression, while: Q = sym ('Q', [2 3]) creates a ‘2 x 3’ symbolic expression. If you want the numeric value of ‘A1’ (or any of the others that do not contain symbolic variables — I did not check all of them to be certain that they do not — refer to them with respect to the ‘sol ...

I try to declare a symbolic variable in MATLAB with this code: syms a; I do my computation on this variable and all thing is fine. But my problem is that, I don't know how can I give a number to variable and get the result as a number. For example the answer of my code is . answer=exp(-10*a); For instance I want to give 40 to "a" and get the ...

Symbolic numbers are exact while double-precision numbers have round-off errors. Convert pi and 1/3 from symbolic form to double precision. symN = sym ( [pi 1/3]) symN = [ pi, 1/3] doubleN = double (symN) doubleN = 3.1416 0.3333.
