m_assert(expr, #expr, __METHOD_NAME__, __FILE__, \\

.PP
A prettier assertion function\&. This macro calls the m_assert function which is a more informative assertion function than the regular assert function from cassert\&.
.PP
Definition at line \fB45\fP of file \fButils\&.hpp\fP\&.
.SS "#define DEBUG(msg)"
.PP
Writes a debug message\&. This macro writes a debug message that includes the filename, line number, and a custom message\&. The function is wrapped in an ifdef that checks if DBG is defined, so one can choose to display the debug messages by adding the -DDBG flag when compiling\&.

.SS "bool arma_vector_close_to (arma::vec & a, arma::vec & b, double tol = \fC1e\-8\fP)"

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\&.

.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
