I tried to give it an honest evaluation, but found it extremely slow on my PC. I have an i7 8CPU @3.6 MHz, with 16 GB of ram and a SSD hard drive. Maybe they have done something in the last couple of months to speed it up.
If I am not mistaken you have to buy both Maple and Maple Flow.
Opened the tutorial to learn the basics. It's going to be a steep learning curve!
In the tutorial (which I would think had been worked to perfection), typed a variable, followed by a colon (for colon/equal) then a number--got a red box "unhandled exception." Typed the variable name in free space, below that typed name = , got "name = name. (Great!) Typed "name:6---got "unhandled exception!" (If I double underline (to create a subscripted name the assignment works, but a simple variable name will not permit a numeric assignment. And this is the tutorial page!
A name with no subscript: you need to type colon and equals (not just colon) to create a definition (the tutorials is in correct according to their tech support)
A name with a subscript: you need to type colon to create a definition
I thought it would be interesting to do a side by side comparison of a relatively simple calculation, so I've compared my response to Fred's question about a weir - see below.
I didn't use units in Maple flow as I couldn't get the plot to work properly with them, though the individual calculations worked ok with them (it's likely that a more experienced Maple flow user would be able to get the plot done with units). There are some syntax differences as might be expected - the above shows a difference in the way functions are defined.
At present I find Mathcad easier to use - but I've been using Mathcad for over 20 years, while I've been using Maple flow for one day!
Maple flow as above, but with symbolics and units:
Thanks for the test. I had trouble getting even that far. Even a few simple calculations took forever.
I also am biased as I have used Mathcad for at least 25 years. But I did want to see if there was a viable alternative. Pricing is a problem with me as well.
