save size of Matlab environment variable

Hi,

I have some question about the presentation of variable in Variables window.

1) I have a matrix with 18 Column. when i look on row of the matrix i want to look on all the data.

I resize the column to be like i want. the problem is that it not saved. when i run the program again with other number of rows or if i run it after i turn down the program the size don't saved and came to the default.

Do matlab have the possibility to save this resize?

2) It have a way to change the variable format show in this window? (my problem is that 12345.6 look 1.2345e4) Same question for a plot, can i change the format of axis (y) to be 12345 and not 1.2345e4?

tnx

If you want to resize a variable and have it stay resized next time you run a program you would have to do the resize in code, or if it is loading the variable from e.g. a .mat file then do the resize and save the updated variable to the mat file before re-running the program.

Preferences -> Command Window -> Format.
Preferences -> Variables -> Format.

control the default formatting of numbers in, respectively, the command window and variable editor. (Note, that is from Preferences in the Matlab Home ribbon, not in code, I just used a code block to split the two instructions for readability). You can change it in the variable editor on a one-time basis from the ribbon at the top.

I don't know about how you can influence the style of number format on axes though.

It the format didn't change in variables only the Command window change.

It does for me if I set both of those parameters. You may need to reopen the variable editor though, or at least close and reopen a variable to see the change (not all notations will show a change either, depending on what the format is and what your data is).

[Yona]

Yes, after i close the variable window it work.

In the list i just didn't find a format i want, but thank you.

[Adam]

Yeah, I don't like most of the formats at all. I think long g or occasionally short g are the only one I find acceptable.
