Question: Working with Maple toolbox for Matlab

I have a big project in matlab that I've been writing for months. It includes a lot of code related to equations. The code worked with Matlab symbolic engine (or maybe it was Mupad I'm not sure). I wanted to switch to Maple symbolic engine so I downloaded Maple toolbox for Matlab. Now I can't run my code anymore since matlab doesn't recognize commands like 'vpasolve' (solve numeric equations), 'children' (finds subexpressions of a given expression), etc..

I'm looking for a long time for a tutorial that explains how to work with Maple toolbox for matlab that can expain in details what changes I need to make in my code to make it work. For example, I have no idea what to write instead of the 'children' command. I didn't find any tutorial. The best I've found so far is this link:

http://www-h.eng.cam.ac.uk/help/tpl/programs/Matlab/maplesymbolic.html

but It explains only a little and I still don't know what to do with many of the commands that I need to change (like 'children').

Can anyone suggest how I can change my code to make it work? or send me a link that explains that (if exists). I know a little Maple (mostly works with Matlab).

I know that ''op'' command in maple is the equivalent to "children" command in matlab. but I still don't know if I should use the command "op" in matlab (for maple engine) or something else.

Also, I have a command "eq=exp1==exp2" (where exp1 and exp2 are 3x3 matrices of symbolic expressions). In Mupad engine it defined eq as a matrix of equations but in maple engine eq is a logical matrix (all zeros). How can I write the equivalent (I mean code in matlab for maple engine)

Thanks!
