pvGetParVector¶

Purpose¶

Retrieves parameter vector from structure of type PV.

Format¶

p = pvGetParVector(p1)¶

Parameters:: p1 (struct) – an instance of structure of type PV
Returns:: p (Kx1 vector) – parameter vector.

Examples¶

// Declare 'p1' as an instance of a 'PV' structure
struct PV p1;

// Initialize 'p1' with default values
p1 = pvCreate;

x = { 1 2,
      3 4 };

// 1's indicate elements to pack into 'p1' parameter vector
mask = { 1 1,
         0 0 };

p1 = pvPackm(p1, x, "X", mask);

print pvUnpack(p1, "X");

pvUnpack() returns the entire value of x that was packed in. Therefore, the print statement above, produces:

1.000 2.000
3.000 4.000

print pvGetParVector(p1);

pvGetParVector() returns only those elements indicated by the mask variable and therefore the print statement above, returns:

1.000
2.000

Remarks¶

Matrices or portions of matrices (stored using a mask) are stored in the structure of type PV as a vector in the p member.
