What is wrong with my code it keeps telling me that i have 'Error: File: labmaterials.m Line: 67 Column: 109 Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters.

Ms(iii)=2/pi*(w1*log*[tan*[acos*[w1/l_vector]]+l_vector/w1]+l_vector*(pi/2)-l_vector*acos*[w1/l_vector])(iii);

The problems are too many to specifically enumerate:

Ms(iii)=2/pi*(w1*log*[tan*[acos*[w1/l_vector]]+l_vector/w1]+l_vector*(pi/2)-l_vector*acos*[w1/l_vector])(iii);

I have no idea what the ‘(iii)’ subscript refers to (I am guessing ‘l_vector’) however it cannot just sit there at the end of the statement, since it does not specifically refer to anything.

I have no idea if this will work and do the calculation you want, however the parentheses and function calls all appear to agree:

Ms(iii) = 2/pi*(w1*log(tan(acos(w1/l_vector(iii)))+l_vector(iii)/w1)+l_vector(iii)*(pi/2)-l_vector(iii)*acos(w1/l_vector(iii)));

Note the changes. Make appropriate edits to get the result you want.

Thank you so much it worked!!

As always, my pleasure!

I guessed correctly!!!
