Comparing terms in a character array

Hey,

I have character array with terms solve= (B*C) + (A*~C), I am comparing terms from table to determine if it exist exact in the character array. I tried.

if strcmp(solve,'A*C')

do nothing

else

" I would to add the term ('A*C') from the if statement into solve"

end

Can anyone assist me in matching if the exact term exist in the array & if not I would to add it to the existing character array.

Thanks.

What is solve? Is it a string?

Solve the character array

If it is truly a "character array" and you want exact matches only, you can use the findstr() command, which will return empty if not found

expr = '(B*C) + (A*~C)'

newterm = '(A*C)'
if isempty(findstr(expr,newterm))
    expr = [expr ' + ' newterm]
end

If your expression is a string as KSSV was asking, you can do

expr = "(B*C) + (A*~C)"

newterm = '(A*C)'
if ~expr.contains(newterm)
    expr = expr + " + " + newterm
end

Thank you. The first part worked well
