One of the great idea of mathcad ( the e-book) is gone ! For example if I need to look at some DSP, I see that some of the DSP examples that used to be in the e-books are now on the net, but the drag and paste doesn't work, and the copy and paste doesn't seem to work well either. and where are the e-books, and the quick links ?! They were great, you could just drag and paste the examples in a split second. Ħ) The hyperlink capability that was allowing me to jump quickly in large files doesn't seem to be supported.ħ). The picture operator needed also to be replaced with contour plots in greyscale, for which the greyscale granularity is not good enough and cannot be modified. ģ) Matlab component is not supported ( but it was not working well in mathcad15), components like the slider and the buttons are not supported.Ĥ) The symbolic equation solver is not supported yet.ĥ) Some of my 3D graphs ( scatter plot for example) need to be substituted for contour plots that are not as good.
You want newer software to be always faster not slower. So speed might be a wash, which is not good. I had to copy and paste pieces of the converted file to see what was working and what was not.ġ) The new "look" of mathcad : I don't know what people think, but mathcad 15 looks more professional to me than Prime, and the rubban don't seem very practical compared to the menus of mathcad15 that seem more intuitive to me, easier and faster to use.Ģ) The speed ? On the same computer, large loops with a log computation in the loop are now almost twice slower with prime 4.0 than they were with Mathcad 15 ! On the other hand, large matrices computation seem to have improved in speed by a factor of 3. so I did that today.įirst I converted a mathcad "capability" file I had for mathcad 15 with all kinds of features to Prime 4.0.įirst conclusion : the converter is quite bad, and basically useless for the numerous complex files I have written in mathcad15 through the years. But now that there was Prime 4.0, I wanted to compare with Mathcad 15 that I know well.
I never looked at Prime, as people were saying that it was not good, and light years from Mathcad 15.
What a bad decision from some managers at PTC ! I just keep thinking about what would have happened if PTC had spent their effort continuing on mathcad 16 instead of going towards Prime, which was a useless effort.
