When converting your worksheet data directly into a matrix, if your X and/or Y data is not evenly spaced the Worksheet: Convert to Matrix: Direct menu operation may fail if the fluctuation in your X, Y steps is beyond a set tolerance value.
You will then need to first use the Worksheet: Convert to XYZ menu. You will get a new sheet with three columns: X Y Z. You can then convert the XYZ data to a matrix using Worksheet: Convert to Matrix: XYZ Gridding.... The process of gridding creates new, interpolated data on a uniformly spaced X and Y grid.
