I have got a problem here.
I want to use solver within a function I m writing. To give you more details, suppose I want to write a function like:
function [a] = example
a = solve('14 = x^2')
end
Now the problem is how I can key in a variable instead of 14 in that solver. I mean suppose I have a variable been defined before like: d = 14, now I want to write my function as below, but it doesn't work :(
function [a] = example
d = 14
a = solve('d = x^2')
end
Any help?

syms x
a = solve(x^2 - d)
Alternately,
d = 14
a = solve(subs(sym('d = x^2'), 'd', d));

If you have a number in symbolic form which does not contain any unresolved symbols, then use double() to convert it to double precision number. Otherwise use char() and print the result as a string.
