How can I select the working dimension by supplying the DIM argument?

While generating C code for below code:

a= [1 2 3 4 5];

u = a/max(a);

I am getting error:

The working dimension was selected automatically, is variable-length, and has length 1 at run time. This is not supported. Manually select the working dimension by supplying the DIM argument.

How can I solve this?

Read the help for max. Look at the various ways you can use the max function.

[Rutvik Shete]

Use elementwise division. u = a./max(a); "dot" is important.

In the Extended Capabilities section of the documentation page for the max function, expand the "C/C++ Code Generation" item. The page linked in the third bullet in that item, "Variable-Sizing Restrictions for Code Generation of Toolbox Functions", offers some explanation and a suggestion for how to resolve the problem.
