.PP
Test if two armadillo vectors are close to each other\&. This function takes in 2 vectors and checks if they are approximately equal to each other given a tolerance\&.

.SS "void m_assert (bool expr, std::string expr_str, std::string func, std::string file, int line, std::string msg)"

.PP
Test an expression, confirm that test is ok, or abort execution\&. This function takes in an expression and prints an OK message if it's true, or it prints a fail message and aborts execution if it fails\&.
.PP
\fBParameters\fP
.RS 4
\fIexpr\fP The expression to be evaluated
