I need help with Matlab if functions

3. The Nusselt number (Nu) is a dimensionless number that corresponds to the ratio of convective to conductive heat transfer. For fluid flow perpendicular to a constant temperature cylinder (a common heat exchanger geometry), Nu cRe"Pr1/3 where Re is the Reynolds number, Pr is the Prandtl number, and c and n are empirical constants Write a function that calculates and outputs Nu given Re and Pr based upon the correlations provided in the table below. Re 1 s Re
