hi, this can't be hard can it?.. am new to mathcad and am trying to import 3 columns x12 rows of excel data by copy/paste into a table and/or a matrix etc with the intention of plotting on a 3d surface graph
...I can paste the values into the mathcad matrix ok but can't seem to assign a variable name to the matrix... so graph can't load it (nor can anything else refer to it I suppose)
...the table rows/columns aren't read in from the excel data - they are presumed 0, 1, 2 etc - so axes are preset to 0, 1, 2... rather than 1st 2 columns of data in excel file - graph just plots 3 columns of data imported as if they were functions f({0, 1, 2}, {0, 1, 2})... which seems a bit dim ...(my 3 columns in excel are the x, y, z) function should be {excel col3} = f({excel col1}, {excel col2})
I must be missing something obvious - can anyone help?
lots of thanks
