*SCAL

*SCAL, Name, Val1, VAL2
Scales a vector or matrix by a constant or a vector.

Argument Descriptions

Name

Name used to identify the vector or matrix to be scaled. Must be specified.

Val1

When scaling a matrix or a vector by a scalar value, Val1 is the real part of the constant to use (default = 1).

When scaling a matrix or a vector by a vector, Val1 is the name of the vector used for the scaling operation.

VAL2

The imaginary part of the constant to use (default = 0). This value is used only if the vector or matrix specified by Name is complex.

VAL2 is only valid for scaling by a constant. It is not used when scaling by a vector.

This command can be applied to vectors and matrices created by the *VEC, *DMAT and *SMAT commands.

Data types must be consistent between the vectors and matrices being scaled and the scaling vector (or constant value).

When scaling a matrix with a vector, the matrix must be square and the scaling vector must be the same size. See examples below.

Scaling a vector by a constant results in all vector values multiplied by the same constant value:

*SCAL,V,2             ! V[i] = V[i]*2

Scaling a matrix by a constant results in all matrix values multiplied by the same constant value:

*SCAL,M,2             ! M[i][j] = M[i][j]*2

The following command scales a complex values vector by a constant value of (2,1):

*SCAL,ZV,2,1          ! ZV[i] = ZV[i] * (2,1)

The following command scales a vector by another vector. All vector values are multiplied by the corresponding value in the scaling vector:

*SCAL,V,W		! V[i] = V[i] * W[i]

The following command scales a matrix by a vector, resulting in all matrix values scaled using the formula below:

*SCAL,M,V		! M[i][j] = M[i][j] * V[i] * V[j]
