Object Model: SIMatrix4.Value

SIMatrix4.Value

Description

Sets or returns the (i,j)th value (Double) of this 4x4 matrix where i represents the rows and j represents the columns.

| m[0,0] m[0,1] m[0,2] m[0,3] |

| m[1,0] m[1,1] m[1,2] m[1,3] |

| m[2,0] m[2,1] m[2,2] m[2,3] |

| m[3,0] m[3,1] m[3,2] m[3,3] |

Tip: Value is the SIMatrix4 object's default property, which means that you can call the method by just using the parenthesis and leaving out the property name for example m(j,i).

C# Syntax

// get accessor
Double ISIMatrix4.get_Value( Int16 in_nRow, Int16 in_nCol );
// set accessor
ISIMatrix4.set_Value( Int16 in_nRow, Int16 in_nCol, Double pVal );

Parameters

Parameter	Type	Description
i	Integer	Specifies the row index.
j	Integer	Specifies the column index.
