Hello :)
I want to arrange in a matrix, for example that's what I got in the software of command window
The strain tensor is
1.0e-04 *
0.0546 -0.1875 0.0625
-0.1875 0.1792 0.3125
0.0625 0.3125 -0.1324
How can do like this : [5.45*10^-6 -1.87*10^-5 .......] (without 1.0e-04 *)
Thanks for the helpers
My code:
clc;
clear;
sigma=input('Insert normal stresses[Mpa] and shear stresse[Mpa] of the cauchy stress tensor:');
format short %fixed-decimal format with a total of 4 digits
sigma_xx=sigma(1,1);
tau_xy=sigma(1,2);
tau_xz=sigma(1,3);
tau_yx=sigma(2,1);
sigma_yy=sigma(2,2);
tau_yz=sigma(2,3);
tau_zx=sigma(3,1);
tau_zy=sigma(3,2);
sigma_zz=sigma(3,3);
disp('The matrix is'); disp(sigma);
Metal = input('Insert type of a metal material:','s');
switch Metal
case 'AISI1020'
S_y = 427;
G = 80000;
v = 0.29;
E = 207000;
case 'Alloy6061-T6'
S_y = 276;
G = 26000;
v = 0.33;
E = 69,000;
case 'SAE4340'
S_y = 910;
G = 83000;
v = 0.29;
E = 214000;
end
epsilon_x=(1/E)*((sigma_xx)-v*((sigma_yy)+(sigma_zz))) ;
epsilon_y=(1/E)*((sigma_yy)-v*((sigma_zz)+(sigma_xx))) ;
epsilon_z=(1/E)*((sigma_zz)-v*((sigma_xx)+(sigma_yy))) ;
gamma_xy=(tau_xy)/(2*G) ;
gamma_xz=(tau_xz)/(2*G) ;
gamma_yz=(tau_yz)/(2*G) ;
gamma_yx=gamma_xy;
gamma_zx=gamma_xz;
gamma_zy=gamma_yz;
epsilon=zeros(3,3);
epsilon(1,1)=epsilon_x;
epsilon(1,2)=gamma_xy;
epsilon(1,3)=gamma_xz;
epsilon(2,1)=gamma_yx;
epsilon(2,2)=epsilon_y;
epsilon(2,3)=gamma_yz;
epsilon(3,1)=gamma_zx;
epsilon(3,2)=gamma_zy;
epsilon(3,3)=epsilon_z;
disp('The strain tensor is'); disp(epsilon)

Consider using sprintf or fprintf instead of disp. This allows you to set the formatting of your output.

As an example
epsilon=1.0e-04 *[
0.0546 -0.1875 0.0625
-0.1875 0.1792 0.3125
0.0625 0.3125 -0.1324];
fprintf('%g %g %g\n',epsilon)
5.46e-06 -1.875e-05 6.25e-06 -1.875e-05 1.792e-05 3.125e-05 6.25e-06 3.125e-05 -1.324e-05

You can change the numeric format in Configuration.
Change Numeric format in command Window.
I hope it helps

Your answer is also good, I Accepted. In my case I had to submit to my the lecturer so we certainly could not change his settings.
Thanks for the help I also learned new things from you :)
