Hello!

This might seem very simple, but if I have created, let's say, the following variables:

A = 1/(10^(-6));
B = 22^(1/4);
C = 4^(3+2);
Now, I should make a vector (named MySolutions) containing the solutions A to C.
Shouldn't it work by writing:
MySolutions = [A,B,C]
The output gives me:
mySolution =
   1.0e+06 *
    1.0000    0.0000    0.0010
    
I don't understand why the output looks so weird.
Any help is appreciated!

Use the format function to change the way they are displayed:

A = 1/(10^(-6));
B = 22^(1/4);
C = 4^(3+2);
format long E
MySolutions = [A,B,C]
format short g
MySolutions = [A,B,C]
format long
MySolutions = [A,B,C]

producing:

MySolutions =
     1.000000000000000e+06     2.165736770667994e+00     1.024000000000000e+03
MySolutions =
        1e+06       2.1657         1024
MySolutions =
   1.0e+06 *
   1.000000000000000   0.000002165736771   0.001024000000000
