I have a matrix "TRPfeat".

It conisits values of

>>TRPfeat

TRPfeat =

1.0e+003 *

0.0398 2.4990 0.0044 0.0010 0.0493 0.1015 2.4910 0.0033 0.0010 0.1826 0.1038 1.5180 0.0036 0.0010 0.1250 0.0733 0.8220 0.0024 0.0010 0.1180 0.0806 0.7420 0.0036 0.0010 0.1260 0.0465 0.7490 0.0033 0.0010 0.0789 0.0295 2.4040 0.0040 0.0010 0.0446 0.0193 2.4990 0.0037 0.0010 0.0254

My problem is, I dont want to use display multiple of 1.0e+003. Simply I need result with precision 6 digits after the decimal point.

How to do this?

If it is just the matter of display, check doc format. try

format long g

Check doc sprintf for details. It's pretty much the same as in C code.

It is not possible with binary floating point numbers to *exactly* store values that have 6 digits after the decimal point (well, there are a small number that can be stored exactly but not many.)

If you take the values and multiply them by 10^6, round() that, and divide by 10^6, the result will be a matrix that will have the closest possible binary floating point numbers to the ones with 6 digits after the decimal point.
