i have encountered a parse error, how do i fix it ?

Hello everyone ,

I am supposed to write a function to calclate the gaze formula ,

i have written this :

function boolanswer = isingaze1 (Xbb,Ybb,cx , cy , a , b , tdegree)

boolanswer = (((Xbb - cx)cos(tdegree)+(Ybb-cy)sin(tdegree))^2)/(a^2)+(((Xbb-cx)sin(tdegree)-(Ybb-cy)cos(tdegree))^2/(b^2)<=1

    
end

but there is an error with the first cos , "Error: File: isingaze1.m Line: 3 Column: 26

Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error. To

construct matrices, use brackets instead of parentheses."

i cannot figure out what the problem is ?

would you please help me ?

what are the input to your function ? all integers (Xbb,Ybb,cx , cy , a , b , tdegree) ?

Also please give the formula.

yes they are ,

i have mentioned the formula , the second line is the formula .

You have terms like:

(Xbb - cx)cos(tdegree)

That's not allowed, you have to explicitly put a '*', '.*' , '/' or a './' between the parenthesises. Also read the error-message and look at your code with intent to understand the error message.
