I am defining a function named corry and inside that function if I read a image using imread I get an error 'The expression to the left of the equals sign is not a valid target for an assignment'
function corry = gandhi_check(img)
{
IReal1 = imread('Real_4.jpg');
_real_check1 = imcrop(IReal1 , [754 123 120 129];
IReal = rgb2gray(IReal1) ;
real_check = rgb2gray(gandhi_real_check1) ;
p = corr2(real_check , img) ;
corry = p ;
}
I am getting error at the line of Imread. Can anyone help me with this error.

Hello Prayag,
MATLAB does not use curly braces { } to demark functions, loops, conditionals, or other code blocks. Instead, MATLAB uses the keyword (like function, for, or if) to denote the beginning, and end statements to indicate the end of the block. I believe that MATLAB is interpreting the curly brace as belonging to the same code line as imread, and is erroring as a result.
