Hi everyone !
I'm new to SMath Studio and find it really great, thanks a lot for this awesome tool !
But I came across a problem I don't find how to solve:
I want to export my data (a big matrix) to a csv file that would be arranged like this:
0.01,201060,237680,198853.285077439
0.015849,143256,185072,174269.293182435
0.025119,93978,149668,133006.974667634
0.03981,57338,110334,83471.8795836333
0.063095,35432,79992,43221.3253258427
0.1,20672,57000,19652.9918548953
0.15849,11280.4,40188,8399.57161545733
0.25119,6361.6,27224,3544.56326448012
.....

For that, I use a matrix to which I add the colums one by one and use the CVS/ODT plugin:
M:=augment(col1;col2)
M:=augment(M;col3)
M:=augment(M;col4)
.....
export_CSV(M,"filename"Wink

And that works fine up to 4 columns... but for a reason I don't understand if I add more columns it ends up writing the file as:
"mat(0.01,201060,237680,198853.285077439,0.015849,143256,185072,174269.293182435,0.025119,93978,149668,133006.974667634......

Can you help me get the same file format with more columns ?

Thanks !

Hello chandragon Offline

could you provide a file with an example that doesn't work for you, I'm not able to reproduce your issue

Give some hint about your matrix:
1. created in Smath as an 2D image ?
2. columns from foreign source or from Smath modules ?
If foreign from source as individual columns
easy to augment via a little piece of program.

Hi and thanks for your answers.
Giving you the .sm file would be complicated because of the plenty of files it opens...
But here is the output file I get:
mydata.7z (5kb) downloaded 38 time(s).
If I remove the " " and try to read it with rfile it gives the value 0.
The matrix I write is pretty big but here is what it looks like when I want to show it:

The number of lines matches.
It is created via a succession of augment() of columns made of real and imaginary parts of complex arrays that are created line by line in a for loop, example for one of them here:

Problem solved using only one augment() call to create the matrix like Davide Carpi did!

Thanks again !

Your collection is not a matrix; it is an MDA [Multi Dimensional Array => Matlab]
or a CELL ARRAY [Mathematica]. No matter, the "collection" can be spooled to file
and recalled from file, just do it the right way as exemplified [attached].
