![]() (see Assign Formula command from the Matrix menu) A GraphĪ graph can contain one or several plots. In the same way as for tables, you can also fill matrix with the results of a function z=f(i,j) in which i and j are row and column numbers, or z=f(x,y). If you want to read a matrix from an ASCII file, you can import the data of the file to a table with the Import Ascii command and then convert this table to a matrix with the Convert to Matrix command. Nevertheless, you can specify the X-values and the Y-values with the Set Coordinates command command from the Matrix menu.Ī matrix can be created by the New→New Matrix command.

In addition, columns can be labelled as errors on X or on Y values (see Set Column as command).Ī table can be created by the New→New Table command. In each table, columns can be labelled as X-values or Y-values for 2D-plotting, or Z-values if you plan to build a 3D-plot. It can also be used to do some calculations and statistical analysis of datas. A table is a spreadsheet which can be used to store the datas you are entering.
