Pressure in U.S. customary units is measured in psi (pound per square inch) In SI metric units pressure is measured in Pa (N/m²). Write a user-define MATLAB function that converts pressure given in units of psi to pressure i units of Pa. For the function name and arguments, use [Pa] = Psi ToPa (psi). The input argument psi is the pressure in units of psi to b converted, and the output argument Pa is the converted pressure in units o Pa (rounded to the nearest integer). Use the function in the Command Win dow to: Ca) Convert 120 psi to units of Pa.

Please help me to make a little matlab or python code to calculate standard deviation of different data that can show the answer and graph the final result, thank you

Plot the curve of the functions given below in Matlab, take t = -10:0.01:10 1. Unit step function.
