Why is my matrix being multiplied by scientific notation?

>> Data = [0.8970, 4000; 0.2310, 8000;0.4500, 5000;0.1340, 12800]

Data =

1.0e+04 *

0.0001 0.4000

0.0000 0.8000

0.0000 0.5000

0.0000 1.2800

This is a double class and 64 bytes. Please help i dont know why its doing this.

Hi Valerie,

Since the data has widely varying values, there usually has to be an overall scaling of some kind. That is what you get in default format. Maybe you would prefer something like this:

format short g
Data

Data =

0.897         4000
0.231         8000
0.45         5000
0.134        12800

See

help format

for lots of other possibilities

Thank you so much!!

That's the default way that double floats are displayed in the command window. It is purely a matter of display. The actual values contained in Data are what you set them to, and have not changed. See format for other display format options that you can set.
