Please help with this Matlab code, and can you explain what you are doing within your code.

Solar panel is receiving radiation from the sun and heating water at a constant rate flowing in the channel over the collector. The dimensions are given in the figure. Calculate the temperature of the collector plate assuming it is insulated on the back and the inlet water temperature is 20oC. Estimate the flow rate of water under steady-state at noon day sun angle, assume an outlet temperature of 50oC. Assume the transmission of the glass is 100% in the visible, but opaque to the infrared with emissivity 0.7 on both sides, and diffuse and gray properties. Indicate clearly assumptions you make and the energy balance used to calculate change in water temperature on the back plate of the collector.
