Scalar Commands
The Scalar Column contains calculator operations which can only be performed on scalar stack entries.
Drop-down menus in this column include Vec? (convert scalar to vector), Trig (trigonometric, containing sin, cos, etc. functions), d/d? (derivative with respect to...), Max and Min (self-explanatory), Gradient, ln (natural logarithm base e), log (logarithm base 10), mean, and Std (standard deviation). Note that the calculator’s Integrate function is located in the Scalar column. The implication is that integration can only be performed on scalar quantities. To perform integration upon complex quantities, you must perform the integration separately on real and imaginary subcomponents.
Use these commands to perform operations on scalar quantities.
|
Makes the scalar quantity in the top register a vector component. |
|
|
Takes the inverse of the scalar quantity in the top register. |
|
|
Raises a scalar quantity to the power you specify. |
|
|
Takes the square root of the quantity in the top register. |
|
|
Performs a selected trigonometric operation on the value in the top register of the calculator stack (Sin, Cos, Tan, ASin, ACos, ATan). Angles are in radians. Additionally, the ATan2 operation is available, which requires two arguments. This operator calculates the arc tangent of the following ratio: The second register in the stack divided by the top register. Example: If the top register value is 1.5, and the second register value is 2, the ATan2 function returns ATan(2/1.5) = 0.5880 radians. All other Trig functions operate on a single argument (top register only). |
|
|
Takes the partial derivative of the quantity in the top register. |
|
|
Takes the integral of a scalar quantity over a volume, surface, or line. To perform integration upon complex quantities, you must perform the integration separately on real and imaginary subcomponents. |
|
|
Computes the minimum of a scalar field quantity on a line, surface, or volume relative to your choice of Value or Position. |
|
|
Computes the maximum of a scalar field quantity on a line, surface, or volume relative to your choice of Value or Position. |
|
|
Takes the gradient of the scalar quantity in the top register. |
|
|
Takes the natural logarithm (base e) of the scalar quantity in the top register. |
|
|
Takes the logarithm (base 10) of the scalar quantity in the top register. |
|
| Takes the mean of the quantity in the top register. | |
| Takes the standard deviation of the quantity in the top register. |
