If I have two functions:

function y = fcn1 %#eml
A = [
     8     1
     3     5
     4     9
];
y = pinv(A);

and

function y = fcn2 %#eml
A = [
     1
     4
];
y = pinv(A);

and build them

% build functions
emlc -c -T rtw:lib -report -d fcn1 fcn1.m
emlc -c -T rtw:lib -report -d fcn2 fcn2.m

I get two versions of svd.c. What is the best way to merge the resulting object files? I want to call these functions from the same code.

Hi Todd,

Just use this idiom emlc -c -T rtw:lib -report -d foo1 fcn1 fcn2

That will product a library with an entry point for fcn1 and fcn2 that shares all the common code like SVD used by both of them.

Thanks, this works. (I should have looked more closely at the help file...) I get an error when it tries to compile the report, but the library builds and works as expected.

I suppose I could build a library (.lib) for each function. Then I would have redundant object code, but at least I would have them all. Can I assume that generated supporting functions with the same name are functionally the same?
