Hi All

Matlab is displaying numbers with 4 decimal places and i hate when it does that for whole numbers. for example i have a matrix C(i) that starts off from 1 down to 150/275. When i multiply it by 275 i get the first entry as 275.0000 and the last as 150.0000 how do i turn that off or instruct it not to do so.

Related to Matlab: Change Number Format to Remove Decimals

1. How do I change the number format in Matlab to remove decimals?

To change the number format in Matlab, you can use the "format" function. For example, to remove decimals, you can use the command "format short" for short numbers or "format long" for longer numbers.

2. Can I specify the number of decimal places to display in Matlab?

Yes, you can use the "format" function with the "short" or "long" options, followed by a number indicating the desired number of decimal places. For example, "format short 2" will display numbers with 2 decimal places.

3. How can I change the number format in Matlab for specific variables?

You can use the "format" function within a specific variable or expression to change its number format. For example, if you want to display a variable "x" with 3 decimal places, you can use the command "format short 3; x" to change the format only for that variable.

4. Is there a way to permanently change the number format in Matlab?

Yes, you can use the "pref" function to permanently change the number format in Matlab. For example, you can use the command "pref('format','short')" to set the default number format to short.

5. Can I change the number format to scientific notation in Matlab?

Yes, you can use the "format" function with the "short e" or "long e" options to display numbers in scientific notation. For example, "format short e" will display numbers in scientific notation with 4 decimal places.
