I'm sorry, I still have some troubles with the adaption:

> restart: with(plots):

> C1 := `<,>`(`<|>`(0, 7.17, 18.11, 34.34, 57.95, 91.84, 139.98, 207.94, 303.48, 437.57, 625.87, 890.96, 1265.91, 1800), `<|>`(.44, .43, .42, .41, .40, .39, .38, .37, .36, .35, .34, .33, .32, .31));

> fit1 := NonlinearFit(a+b1*exp(-t/c1)+b2*exp(-t/c2), C1[1, 1] .. C1[14, 1], C1[1, 2] .. C1[14, 2], t);

> graph1 := pointplot(C1, symbol = BOX, axes = BOXED);


> display({graph1,fit1});

this is the complete Maple-Code. I'm not sure, how to adapt the fitting in this code. Do you know what I made wrong? The fitting should be also plotted in the diagramm; over the pointplot.

Thank you

Thank you

Thank you very much, it works perfectly!

HI,

thanks for the answer! But thats not exactly what I want. I don't need a blank sign. I need this "space" or "formatting" like if you press the "tabulator"-key. The problem is, that this txt-file will be opened and used by a machine for etching some chemical stuff. And this machine only recognizes "tabs" like from the tab-key. Do you have any idea how I could produce that? :-(

I have to add, that I work with Maple 15
