I want to using solve function for a simple arithmetic equation. But one of the value is an array so I must have array of answers. I am unable to achieve this using solve & maple.solve


As the last resort I had to solve the equation separately which is both boring & not dynamic. The equation has units...

Thanks for the solution. Can you please explain why we need to vectorize (above arrow) the last statement?
Secondly I cannot add units to x in the function developed st_mass? My version is 0.99 (6671)

If the function uses a scalar and you substitute a vector of values, then you need to either use a loop over the elements of the vector, or the vectorization operator.

Try to multiply x by 1 and replace 1 with units.

And I think that the maple() function is not needed here, an ordinary solve() should handle it.

Per my experience maple.solve handles units far better... However still I am not able to reproduce your results.
Sheet is attached, may be my version is old?

Keep in mind that the function maple() doesn't know anything about units at all. The function uses a special trick to ignore them in its work.

Try now

Here is Engineer style ... no need for Maple, just native Smath
Attached SS 6179 ... some volunteer to make it unit kg/s

Hi. I guess that the problem is that kw just like "kw" both in lowercase isn't an unit, but it is kW. To know the name of an unit you have the coup icon for insert one in the toolbar.

In the attached using kW instead kw, maple don't needs units manipulation, but SMath's roots needs.

Best regards.

... forget units, reconciliate as you wish in the solve bloc & Table
