y = A(1, sin (end));From that line alone, it is not clear what end refers to. If sin is a matrix, then end will be the end of sin. If sin is a function, then end will be the end of A.

I have solved this problem by keeping track of the full context information for each end. Lets take a look at a slightly more complicated example

y = A(1, 2, B(sin (end), 5));then during type inference our context might look something like this

type identifier index count function sin 0 1 matrix B 0 2 matrix A 2 4In this context end then refers to the end of matrix B at index 0.
