Multiply Each Cell Value in Double by 1000

I have a 10801x1 double saved as variable x1 in my workspace and I want to multiply each cell within that double by 1000 and then save the variable as a .txt file, is there a way to do this?

"I want to multiply each cell within that double"

They are referred as elements not cells, as cells in MATLAB mean something else.

Cell Arrays

your_variable=randi(400,10801,1);
out=your_variable*1000;
writematrix(out,'mytextfile.txt')

Could you elaborate what the randi means and where you got the 400 value from?

[Arif Hoq]

randi is a function to generate random number integer. Here generated random integer number between 1 to 400.

I dont have your variable x1. so I have generated a random number.

Where does 'mytextile.txt' get saved? is there a way to specific the directory?

[Dyuman Joshi]

"Where does 'mytextile.txt' get saved?"

The file gets saved In the current directory. You can find that by typing the command "pwd" in your command line.

"is there a way to specific the directory?"

Yes, refer here - writematrix filename

Hi there!

You can use the following code to accomplish what you want:

x1 = x1 * 1000;
dlmwrite('output.txt', x1, 'delimiter', '\n');

The first line multiplies each cell in the array by 1000.

The second line writes the modified array to a text file "output.txt" where each of the cell value occurs in a new line.
