I am using Matlab coder to port code to C, e.g. for the next function:
function sum_out = my_sum( x )
sum_out = 0;
for i=1:size(x,1)
sum_out = sum_out + x(i);
The generated C code is:
double my_sum(const double x[10])
double sum_out;
int i;
sum_out = 0.0;
for (i = 0; i < 10; i++) {
sum_out += x[i];
return sum_out;
Is there a way to make the indentation 4 spaces? Also, I would like to have the curly brackets in a separate line.

The Coder configuration settings IndentSize and IndentStyle will let you achieve the changes you want:

I am trying to convert this simple code into excutable using matlab coder.
function y = hello_world
y = 'Hello World!';
converting to source code C works but when i change the build type to Executable
It gives me this error:
Build error: C compiler produced errors. See the Build Log for further details.

I suggest posting new question rather than adding a question as an answer to an existing post. We frequently monitor new questions. New comments and answers may not be seen.
The linker error you see means that a C main function wasn't supplied as is required to compile an executable. The Documentation describes this in more detail with an example.
