Method Details
-
get
float get(int row, int col) Returns the value of value of the specified matrix element.- Parameters:
row
- Matrix element's row index..col
- Matrix element's column index.- Returns:
- The specified element's value.
-
unsafe_get
float unsafe_get(int row, int col) Same asget(int, int)
but does not perform bounds check on input parameters. This results in about a 25% speed increase but potentially sacrifices stability and makes it more difficult to track down simple errors. It is not recommended that this function be used, except in highly optimized code where the bounds are implicitly being checked.- Parameters:
row
- Matrix element's row index..col
- Matrix element's column index.- Returns:
- The specified element's value.
-
set
void set(int row, int col, float val) Sets the value of the specified matrix element.- Parameters:
row
- Matrix element's row index..col
- Matrix element's column index.val
- The element's new value.
-
unsafe_set
void unsafe_set(int row, int col, float val) Same asMatrix.setTo(org.ejml.data.Matrix)
but does not perform bounds check on input parameters. This results in about a 25% speed increase but potentially sacrifices stability and makes it more difficult to track down simple errors. It is not recommended that this function be used, except in highly optimized code where the bounds are implicitly being checked.- Parameters:
row
- Matrix element's row index..col
- Matrix element's column index.val
- The element's new value.
-
getNumElements
default int getNumElements()Returns the number of elements in this matrix, which is the number of rows times the number of columns.- Returns:
- Number of elements in this matrix.
