Hi,

I am assuming you want to know how to read data from excel files in your code. You can do so using readtable. You might find examples from this link useful.

Also, if you have any "specific" doubts in the implementation of the algorithm from the given flowchart, you can let us know

Hope this helps!

This is my flowchart.

I have tried doing the coding. I have mention the coding below. Its showing error most of the time. Can someone help myself to rectify the coding

% This program is to assign the Stability and Determinacy of Structure Beam

% and Truss

function main()

% Gethering input

Structure = input("Choose your structure '1-2': ",'s');

while Structure == '1'

r = input("Enter number of reaction: ");

n = input("Enter number of internal hinge: ");

X= n + 3;

if r < X

Beam = 'Statistical Unstable';

elseif r == X

Beam = 'Determinate';

elseif r > X

Beam = 'Indeterminate';

end

fprintf ("\n");

fprintf ("Your beam is %s",Beam);

fprintf("\n\n");

Without knowing what errors you're receiving and what you entered at all those input statements it's going to be very difficult for us to help you determine why the code isn't behaving as you expect.

Instead, I recommend you use the debugging tools included in MATLAB to step through your code, line by line, as you follow along in your flowchart. Check as you execute each line that it moves you to the box in the flowchart you expect and when it doesn't, determine why not.
