Why are the matrix numbers changing?

I'm trying to write a matrix but the numbers are changing. What could be the reason?

"I'm trying to write a matrix but the numbers are changing. What could be the reason?"

The values are not changing. You are mixing up two different things:

• how numeric values are stored in memory
• how numeric values are displayed as text (e.g. in the command window).

There is no one canononical way to display numbers (or numeric values), what you see are simply those values displayed using the default display FORMAT (which happens to have four decimal places and a common multiplier in the top left corner). Use the FORMAT function if you want some other display format.

The numbers are not changing, the default display format is such.

A = [1.08 -1 0; 2184.02 -2185.02 1;0 -1 1.81]

A = 3×3

1.0e+03 * 0.0011 -0.0010 0 2.1840 -2.1850 0.0010 0 -0.0010 0.0018

%Change the output display format to shortG
format shortG
%see the change
A

A = 3×3

1.0e+00 * 1.08 -1 0 2184 -2185 1 0 -1 1.81

%change the format back to default and check the output
format default
A

A = 3×3

1.0e+03 * 0.0011 -0.0010 0 2.1840 -2.1850 0.0010 0 -0.0010 0.0018
