matrix
An Origin C matrix (lower case m) is a dynamically allocated and sized two dimensional array that is not tied to an internal Origin matrix allowing a greater degree of flexibility. matrix is a template class with a default type of double but a matrix of any basic data type (including char, byte, short, word, int, uint and complex but not string) can be constructed using the syntax matrix<type>. The matrix class is derived from the matrixbase class from which it inherits methods and properties.

void matrix_ex1() { int ii, jj; matrix<int> mInts = {{1,2,3},{4,5,6},{7,8,9}}; printf("mInts:\n"); for(ii = 0; ii < mInts.GetNumRows(); ii++) { for(jj = 0; jj < mInts.GetNumCols(); jj++) printf("%d\t",mInts[ii][jj]); printf("\n"); } matrix mDoublesByDefault = {{1.1,2.2,3.3},{4.4,5.5,6.6},{7.7,8.8,9.9}}; printf("mDoublesByDefault:\n"); for(ii = 0; ii < mDoublesByDefault.GetNumRows(); ii++) { for(jj = 0; jj < mDoublesByDefault.GetNumCols(); jj++) printf("%g\t",mDoublesByDefault[ii][jj]); printf("\n"); } }
