What does the command A <- A[,-1] do ?

What does the command A <- A[,-1] do ?

[Adam]

It produces this by default

Undefined function or variable 'A'.

Or this if A is defined as a double

Error: "A" was previously used as a variable, conflicting with its use here as the name of a function or
command.
See "How MATLAB Recognizes Command Syntax" in the MATLAB documentation for details.

or probably a variety of other error messages too!

I have no idea, most of all because it is not a MATLAB command.

1. There is no "<-" operator in Matlab
2. You cannot apply an indexing by square brackets, so "A[]" is not recognized
3. Indexing works with round parentheses: "A()", but then the index ",-1" cannot start with a command and cannot be negative.

So this is simply not Matlab. The answer is: It produces an error.
