No. Learn some other languages and then Matlab's limitations become apparent. It's a decent calculator and a shit general purpose language. Fine for quick prototyping and experimentation.

Array starts from 1.No.

based

Yeah simulink os the real treat here, otherwise you can get scilab and do everything matlab does but for free

not based

it's unstructured and I hate it

Yes, but maple is better for that.

Simscape and certified toolboxes are a huge plus too.
