trying to solve a computer problem of mechanics of material

Hey guys, I'm trying to learn how to use Matlab and I decided to solve some of mechanics of materials ( Beer and Johnston's Mechanics of Materials) computer problems with Matlab to learn how to actually do it, but man I really cant do it and I'm struggeling right now.

The problem that I'm trying to solve atm is 9-C5 which im gonna put the way to solve it on paper in a pic on this post. But I have no idea to actually Code it... I mean I tried some codes but i end up getting wrong answers so I decided to get some help and ask you guys that if it was you how would u write this program? or if its possible can you give me a Hint or help on it?

What this question wants is a input for L, w ,E ,I ,delta_a and outputs like this:

a=0 | theta = 0.7 | y= 1.3

a=0+delta_a | theta= new number using new a | y= new number using new a

.

.

.

a=L | theta = | y=

.I managed to write a code that looks right. I guess i gotta change the question now, how can i ask matlab to write the answers in a excel file like this:

A | B | C

distance | theta | y

a=0 | 0.7 | 1.6

also is it possible to somehow plot the answers i get in each loop?

here is the code (yup I butchered coding world with my zero skills haha)

clc;

clear all;

%Vorodi Haye Karbar%

L = input("Enter the length of the beam? ");

W = input("Enter the Weight on the beam? ");

Delta_a = input("Enter the Delta a? ");

E = input("Enter the Young's Modulus? ");

I = input("Enter the Moments of the section? ");

n= L/Delta_a;

N=n+1; %this line is uselesss now i guess but i saved it as a idea%

while n>-1

x=n*Delta_a;

R=(W/((L)^3))*(((x)^4)-(4*L*((x)^3))+(6*((L)^2)*((x)^2)))';

T=((R*((x)^2))/(2*E*I))-((W*((L)^3))/(6*E*I))';

Y=((R*((x)^3))/(3*E*I))+(L-x)*((R*((x)^2))/(2*E*I))-((W*((L)^4))/(8*E*I))';

fprintf('T= #%d\n', T);

fprintf('Y= #%d\n', Y);

n=n-1;

end
