 2 | % Converting multiple 2D table data from Comsol into a single csv file with
 3 | % 3D data
 4 | % Input files: csv files exported from comsol with XY plane data of a
 5 | % function, fx(x,y,zo). Each file has data for a different zo file.
 6 | % This will be repeated for other functions fy(x,y,zo) and fz(x,yo,zo)

 9 | %   Column 1: x value (space coordinate)

12 | %   Column 5: fy value (function 2)

7 | Combines multiple csv files into a single csv file. The input csv files contains data of a 2D sweep (i.e. F(x,y,zo) is evaluated when x and y are varied and zo is kept constant). Each input csv file is evaluated for a different value of the third parameter (zo is different for each csv file). The output csv file combines the input files to create tabulated F(x,y,z) values where all three variables are swept. This csv file can be used to make a mat file.
