inherited |
Grows or shrinks the matrix to the requested size, if necessary
The new entries are filled with zeros. Obsolete entries are removed.
num_rows | the number of rows |
num_cols | the number of columns |
|
inherited |
Get the transpose of the matrix, i.e. a matrix where rows and columns are interchanged
|
getinherited |
True if the matrix is stored in a symmetric manner, false otherwise
Also true for skew symmetric matrices that exploit this property in order to save memory
|
get |
