vec2ind is not supported for code generation. Is there any other way to solve this issue?

In R2016b notation,
sum((1:size(vec,1)).' .* vec)
In earlier releases you would need
sum( repmat((1:size(vec,1)).', 1, size(vec,2)) .* vec)

The code doesn't give same result as vec2ind
for example vec= [1;0;1;0;1;1;5;0]
The result of vec2ind is 7.
The result of sum((1:size(vec,1)).' .* vec) is 50.
How can get exactly same result?. Becaue I want to transfer matlab code to c++.
Thank you.
