Reading Workspace variable into csv file

10 次查看(过去 30 天)
I got above 22 side bands output from 3D DWT, which are represented in the form of matrix. I need to read this into the csv file. Can anyone help me out???

You misunderstand me. Your matrix is 3D. There are many ways to encode that information into a file that contains comma separated values. Some programs/formats require you to put the coordinates first, followed by the value, with one line per value.
You see the route that Mathworks has chose to display the data: page by page. You could do that as well, but is your program able to understand you mean 17x19x17 instead of 17x323?

Yes, another program requires in 17x323 format.

The most important thing to do first is to reshape the data to a 2D array. Then we can use the writematrix function as normal.
WT.dec{1,1}=rand(17,19,17);%generate random data
d=WT.dec{1, 1};%store in other variable for shorter syntax
%option 1: 17x323
d1=reshape(d,size(d,1),[]);
%option 2: 289x19
d2=mat2cell(d,size(d,1),size(d,2),ones(1,size(d,3)));
d2=cell2mat(d2(:));
filename='d1.csv';
writematrix(d1,filename)

What program concluded the file is corrupt? A text editor or your target software?
