Input

MatrixLayer

<active>

Specifies the input matrix A.

B imb

Input

MatrixLayer

<active>

Specifies the input matrix B.

A-B oms

Output

MatrixObject

<input>

Specifies the output matrix. Get the result of element-wise arithmetic on two matrices.

See the syntax here.

Formula formula

Input

string

<input>

Input the formula for two matrices arithmetic

Note: Add, subtract, multiply, divide and power (+-*/^) are supported in the formula.

Active Matrix in A active

Input

int

0

Specifies whether use the active matrix object in A sheet to arithmetic. If not, use each object in the A sheet will use to arithmetic.

Option List:

  • 0=false
  • 1=true
B Selection option

Input

int

0

Specifies the matrix objects in B sheet for arithmetic.

Option List:

  • 0=active:Active matrix in B
    Active matrix object in B sheet
  • 1=first:First matrix in B
    First matrix object in B sheet
  • 2=same:Same matrix in B
    Perform arithmetic on the matrix object in B with the same index number as the active matrix object in A.
    Note: this option is available, when Active Matrix in A is selected (active=1).
  • 3=all:All matrices in both sheets
    Perform arithmetic on each matrix object in B by the matrix object in A with the same index number.
    Note: this option is available, when Active Matrix in A is unselected (active=0).
  • 4=periodic:Periodic matrices in B
    Perform arithmetic on each matrix object in B by incrementing through (a generally much larger set of) matrix objects in A, from index number = 1 to = end. This option could be used, for instance, when subtracting a monthly mean derived from a long time period of monthly readings, from the monthly readings, themselves.
