Please solve using matlab The rectangular cross section of a long bar $\backslash (($k$=5\backslash$mathrm$\{$~W$\}/\backslash$mathrm$\{$mC$\})\backslash )$ is shown in the Figure below. The bar has convection on the top surface, a temperature boundary condition on the right side, radiation on the bottom, and is insulated on the left side.

$($a$)$ What are the steady$-$state nodal temperatures? Save the temperature at each node in variablename "Node$1"$ for T$(1),$ "Node$2"$ for T$(2),$ etc.

$($b$)$ What is the rate of heat flow to the fluid from the top surface per meter length of the bar? Save the value in varaiablename "qtop"

$($c$)$ What is the rate of heat flow to the surroundings from the bottom surface per meter length of the bar? Save the value in variablename "qbot"
