The user should input how to give the section and for that calculate we must write a code to calculate the Centroid and Moment of Inertia.

Means that the user must define different types of section( like I section, T section circular and elliptical ),so how to input those sections and calculate centroid and moment of inertia for those.

I guess you'd have to provide the [x,y] array of vertices of your shape and then create a matrix out of it which is 1 inside and 0 outside (you can use inpolygon)
Then you can use the regionprops function which can provide a lot information such as the Centroid.
By moment of inertia I guess you mean the second moment of area. Here's the formula for a given polygon.
