Output two of three columns from a surf file to a text file

Hi,

I am using an equation to create a surf plot. It has a large amount of data points. I would like to output the data to a text file (I need Z and X or Y values but not both, a cross section). Unfortunately when I use

dlmwrite('g.txt',[Y,z],'delimiter', '\t');

Or similar, I get a huge array of numbers which I can't interpret for plotting.

I'd really appreciate any suggestions,

Thanks

What does size([Y,z]) return? What makes you think the output is wrong?

Hi, thanks for your response.

I get a 23mb file with 1000 columns and 1000 rows. The problem is, that I would like these to be for just one (arbitrary) x value. Instead I have no idea whether they are for 1 x value or different x values.

I would like 1 column of 1000 z values and the corresponding column of 1000 Y values for 1 specific x value (would be nice but not necessary to define this value).
