I was curious to see how units would be handled in matrices. So I tried a few things and was suprised how well it worked. See screen shot below. Great job. Well thought out. Remeber everthing is calculated in SI units but comes out fine in US/Imperial units.  |

Another advantage of SMath over Mathcad is for matrix elements to have any units and the math is performed correctly. This matrix and multiplication of its elements is not possible in Mathcad.  |

How do these US units work? If I take a simple force in kips multiplied by a moment arm in ft I get result in J....then when I try to change units to kip ft by adding kip, I get m kip...then when trying to get to kip ft I get kgm^2 kip'ft ________________ (s^2)kip'ft Following from cut and paste.... el(F,1)*el(A,2)=225.97*{'kg*'m^2}/{'s^2*''kipft}@''kipft Also, how do you get the units outside the matrix? I can only put units immediately after the cell values. Thanks for any responses. Edited by user 30 August 2012 09:39:13(UTC)

Thank you, was trying not to type but rather use the drop-down to insert units. It appears the "*" was the missing element to that effort. Appreciate your input and the attachment. Originally Posted by: w3b5urf3r_reloaded  Hi ralfsnell, simply type in the right placeholder regards, w3b5urf3r

When using a matrix with elements of a variety of units, is there a way to control the display of the resulting units (imperial instead of SI units)? For instance, in the attached image: k'(1,1) = A(in^2)*E(ksi)/L(in) = kip/inch, but results are in kg/s^2 k'(3,2) = 6 * E(ksi) * I(in^4) / L^2(in^2) = kip, but results are in kg*m/s^2

Hello

, Originally Posted by: justhumm When using a matrix with elements of a variety of units, is there a way to control the display of the resulting units (imperial instead of SI units)? You can try using Code:OutputUnitsSystem=Imperial
instead of in Code:%APPDATA%\Smath\settings.inf
(it is an experimental feature) |

Davide Carpi: Thanks for the response! It seems to be working. Wishlist item: It would be nice to have the ability to switch between feet and inches for the default imperial unit. :-)
