CMatrix:Init
The Init method sets the first n x m CMatrix members to the same value.
|
CMatrix:Init( n, m, value=0 ) |
n is the number of rows to define.
m is the number of columns to set.
value is the target value to assign and may be a
number, string, or other value. If omitted, it defaults to the
number 0.
This method first empties the CMatrix and then defines all matrix members at row indices 1 ... n and column indices 1 ... m. After Init, the Cols method returns m and Rows returns n.
The following script fragment fills a matrix of 8 rows x 4 columns with the number -1.5:
|
M = CMatrix:new() |
-- create a CMatrix |
|
M:Init( 8, 4, -1.5 ) |
-- set first 32 members |
|
Printf("M[5][3] = %lg", M:Get(5,3)) |
-- result: M[5][3] = -1.5 |
The script fragment below initializes a 5x5 matrix to all 0's:
|
M = CMatrix:new() |
-- create a CMatrix |
|
M:Init( 5, 5 ) |
-- set first 5 x 5 members to 0 |
|
Printf("M[3][3] = %lg", M:Get(3,3) ) |
-- result: M[3][3] = 0 |
