function [ C ] = Q3( x )
% let x1 denote t
% let x2 denote q
C = 13.9 + (58.056*((x(1)).^-0.3017)) + ((11.2657*((x(1)).^0.4925)/((x(2)).*1)) + ((0.4491*((x(1))^0.7952)/((x(2))) + ((0.06719*(2*((x(1))) + 1.2*(x(2))).^0.861)/(x(2))))+0.0450*(2*(x(1))) + 1.2*(x(2))) + 14.002*((x(2)).^-0.1899)+ 0.0002914*(((x(2)).^0.671);
is there an error with the code? Pls answer and correct it for me. This is my m-file for using fminsearch, but I kept on getting these errors
Error: File: Q3.m Line: 4 Column: 258
Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters.

Always break long equation to pieces:
C = 13.9 + 58.056*(x(1).^-0.3017) + ...
(11.2657*(x(1).^(0.4925)))/(x(2).*1) + ...
0.4491*x(1)^(0.7952)/x(2) +...
0.06719*2*x(1) + ...
(1.2*(x(2).^0.861))/(x(2))+0.0450*2*x(1) +...
1.2*x(2) + 14.002*x(2).^(-0.1899)+ 0.0002914*x(2).^(0.671);

YOu for got to add one bracket.Check the below lines.....the braces are added properly.
C = 13.9 + (58.056*((x(1)).^-0.3017)) + .......
((11.2657*((x(1)).^0.4925)/((x(2)).*1))) + ......
((0.4491*((x(1))^0.7952)/((x(2))) + .......
((0.06719*(2*((x(1))) + 1.2*(x(2))).^0.861)/(x(2))))+.......
0.0450*(2*(x(1))) + 1.2*(x(2))) +......
14.002*((x(2)).^-0.1899)+ 0.0002914*(((x(2)).^0.671));
