matlab矩阵科学记法

Question

I've wondered about this for a while now. When Matlab prints the matrix A, for instance, with

A

it sometimes appears in scientific notation such as

A =

    1.0e+03 *

         0         0    0.0070    0.0080    0.0030    0.0010
         0    0.0030   -0.0460    0.0400   -0.0930    0.1800
    0.0010   -0.0530   -0.0140   -0.0620    0.0790   -1.2360
    0.0020    0.0009   -0.0032    0.0016    0.0023   -1.4180
    0.0070   -0.0000   -0.0006   -0.0000         0         0

Does anyone know how to make it print normal floating point numbers? I've tried format short, format long, format short e, format long e, but none of them work. Some switch the formatting so that the scientific notation is within individual entries, but really these numbers aren't that ridiculous to just print out...

Answer 1

You can use:

format shortG

See format documentation for more details.

Answer 2

如果您使用的是fprintf，您可以在格式中使用％f ，同时也允许您需要的小数点数，例如％。2f ，它在小数点后总是只给出两位小数
