this is code is for maximizing the sizes of the cantiliver beam in graphical method of linear programming. i just want to ask a little idea how to transfer it in simplex method.

clear all; close all; clc; FOS= input(' Enter the value for FOS= '); F= input('Enter Force= '); L= input('Length= '); E= input('Enter Youngs Modulus for Material= '); sigma_y= input('Yield Stress of the Material= '); def= input(' Maximum allowable deflection= '); a= input(' Minimum depth of the beam= '); b= input(' Maximum depth of the beam= '); constrain1= 6*F*(L)*FOS/sigma_y;

x1= a:0.1:b; [r,c]=size(x1); x2=x1; for i=1:1:c x2(1,i)=constrain1/x1(1,i)^2; end constrain2=4*F*(L^3)/E*def; x3=x1; for i=1:1:c x3(1,i)=constrain2/x1(1,i)^3; end plot(x1,x2,x1,x3);

thank you very much for your kind response.

give all your input datas to test and simplify . select the whole code and press the code button{} so that its easy to read

在 MATLAB Online 中打开

clear all;
close all;
clc;
FOS= input(' Enter the value for FOS= ');
F= input('Enter Force= ');
L= input('Length= ');
E= input('Enter Youngs Modulus for Material= ');
sigma_y= input('Yield Stress of the Material= ');
def= input(' Maximum allowable deflection= ');
a= input(' Minimum depth of the beam= ');
b= input(' Maximum depth of the beam= ');
darshan1= 6*F*(L)*FOS/sigma_y;
x1= a:0.001:b;
[r,c]=size(x1);
x2=x1;
for i=1:1:c
x2(1,i)=darshan1/x1(1,i)^2;
end
darshan2=4*F*(L^3)/E*def;
x3=x1;
for i=1:1:c
x3(1,i)=darshan2/x1(1,i)^3;
end
plot(x1,x2,x1,x3);

thank you sir madhan ravi.
