Relational operators. MATLAB uses the following relational operators. The relational operators have equal precedence among them and MATLAB evalutaes them in order from left to right.

$\backslash$table$[[$Relational Operator,Description$],[,$Less than$],[6=,$Less than or equal to$],[4,$Greater than$],[7=,$Greater than or equal to$],[,$Equal to$],[,$Not equal to$]]$

The result of the comparison is either $1($True$)$ or $0($False$).$

EXAMple $1.$ Comparison of scalars: Civen $x=3$ and $y=5,$ using MATLAB evaluate $xy$ and $z=y.$

EXAMPLE $2.$ Comparison of arrays Given $x=[6,3,9]$ and $y=[14,2,9],$ using MATLAB evaluate $xy$ and $xy.$ MATLAB compares the arrays element by element.

Example $3.$ Given $A=\left[\begin{array}{cc}3& 0\\ -4& 8\end{array}\right],$ find $-A$

ExAMPLE $4.$ Given $A=\left[\begin{array}{ccc}2& 0& -5\\ 0& -3& 9\end{array}\right]$ and $B=\left[\begin{array}{ccc}-3& 5& -7\\ 0& 1& 8\end{array}\right]$ find $A$&$B,A|B|.$
