MATLAB coder gives multiple errors for hierarchical code

I am trying to convert a regression model I generated from regression learner to C for an iOS implementation. The testbench of the function is predictX_test.m and the function to be translated is predictX010.m. predictX010.m relies on mypadcat and mystrsplit to do data pre-processing operations. The code works perfectly in MATLAB but the MATLAB coder doesn't like dynamic memory changes. The errors are shown in the image below, and they occur even in the presence of coder.varsize() calls. What can I do to make them go away?

Use coder.varsize with explicit size specification where applicable. coder.varsize cannot be used on internal function input/output arguments and some modifications need to be done to the code to enable code generation. Also explictly use real(..) when complexity of the double expression is not inferrred correctly.

Please find the attached source for modifications.
