dlmwrite 0 to 0.0

I am using dlmwrite to create two columns in a text file. The first column contains numbers (a=[1:1:100]) and then second column contains zeros (b=zeros(100,1). I then concatenated them and replaced some of the zeros with numbers. When written to a file I need the zeros to display as 0.0 instead of 0. I currently have it written to a .txt file.

Use 'precision', '%.1f' for dlmwrite()

Can I have a different precision for different columns in dlmwrite?

Sorry, that is not possible with dlmwrite(). You should fopen/fprintf/fclose for that.
