To start using QGenericMatrix in your Qt project, you need to follow these steps:
#include <QGenericMatrix>
QGenericMatrix<3, 3, float> matrix;
This creates a 3x3 matrix with float data type.
matrix.setRow(0, QVector3D(1.0f, 0.0f, 0.0f));
matrix.setRow(1, QVector3D(0.0f, 1.0f, 0.0f));
matrix.setRow(2, QVector3D(0.0f, 0.0f, 1.0f));
This sets the values of the identity matrix to the variable 'matrix'.
QVector3D row = matrix.row(1);
QVector3D column = matrix.column(2);
QGenericMatrix<3, 3, float> result = matrix * matrix;
This multiplies the matrix with itself and stores the result in 'result'.
Overall, QGenericMatrix provides a convenient way to work with matrices of various dimensions and data types.
