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
