write from cell aray to txt file

I have a cell array like this:

I want to write it line by line into a txt file (so I can chose which line to write whith an if), I also have to put a whitespace between every cell like this:

the number of whitespaces beetween each cell doesn' t make any difference, I can' t figure out how to write it (the cell array is pretty large so an optimized solution would be handy)

thank you for the support in advance

You have a cell array of char arrays, so the obvious way to write that is with a loop. Are you able to write text to a file?

I guess with a fprintf loop? But I dont know how to manage spaces in an optimized way

fprintf example <<Tabular text file> illustrates a fixed-width text file...if that's the intent use the width parameter on the '%s' and other format strings as you desire.

If the point is to just write a delimited file, then cellwrite is the simplest route -- if you don't want all rows, then create a logical addressing vector of those that are to be written and use it to only select the rows wanted when pass the array.

Thank you!😉

Glad to help...

"...create a logical addressing vector of those that are to be written and use it to only select the rows wanted..."

NB: If those to skip is a much shorter/easier thing to code, then use it and negate the sense with cellwrite(C(~iSkip,:),...)

Thank you, I didnt know that matlab feature to negate the index of the array, very helpful!
