Detailed Description

template<class T>
class casacore::Matrix< T >

A 2-D Specialization of the Array class.

Review Status

Reviewed By:: UNKNOWN
Date Reviewed:: before2004/08/25

Matrix objects are two-dimensional specializations (e.g., more convenient and efficient indexing) of the general Array class. You might also want to look at the Array documentation to see inherited functionality. A tutorial on using the array classes in general is available in the "AIPS++ Programming Manual".

Generally the member functions of Array are also available in Matrix versions which take a pair of integers where the array needs an IPosition. Since the Matrix is two-dimensional, the IPositions are overkill, although you may use those versions if you want to.

Matrix<Int> mi(100,100); // Shape is 100x100

mi.resize(50,50); // Shape now 50x50

Slices may be taken with the Slice class. To take a slice, one "indexes" with one Slice(start, length, inc) for each axis, where end and inc are optional. Additionally, there are row(), column() and diagonal() member functions which return Vector's which refer to the storage back in the Matrix:

Matrix<Float> mf(100, 100);

mf.diagonal() = 1;

Correct indexing order of a matrix is:

Matrix<Int> mi(n1,n2)                  // [nrow, ncolumn]
for (uInt j=0; j<mi.ncolumn(); j++) {
for (uInt i=0; i<mi.nrow(); i++) {
mi(i,j) = i*j;
}      
}

Element-by-element arithmetic and logical operations are available (in aips/ArrayMath.h and aips/ArrayLogical.h). Other Matrix operations (e.g. LU decomposition) are available, and more appear periodically.

As with the Arrays, if the preprocessor symbol AIPS_DEBUG is defined at compile time invariants will be checked on entry to most member functions. Additionally, if AIPS_ARRAY_INDEX_CHECK is defined index operations will be bounds-checked. Neither of these should be defined for production code.

Matrix<T>& casacore::Matrix< T >::operator= ( const Matrix< T > & other )

Copy the values from other to this Matrix.

If this matrix has zero elements then it will resize to be the same shape as other; otherwise other must conform to this. Note that the assign function can be used to assign a non-conforming matrix.

template<class T>

virtual Array<T>& casacore::Matrix< T >::operator= ( const Array< T > & other )

virtual

Copy the values in other to this.

If the array on the left hand side has no elements, then it is resized to be the same size as as the array on the right hand side. Otherwise, the arrays must conform (same shapes).

IPosition shape(2,10,10);     // some shape
Array<Double> ad(shape);
//..\.
Array<Double> ad2;            // N.B. ad2.nelements() == 0
ad2 = ad;                     // ad2 resizes, then elements
//     are copied.
shape = 20;
Array<Double> ad3(shape);
ad3 = ad;                     // Error: arrays do not conform

Note that the assign function can be used to assign a non-conforming array.

behaves as if val were a constant conformant matrix.

virtual void casacore::Matrix< T >::resize ( )

virtual

Make this array a different shape.

If copyValues==True the old values are copied over to the new array. Copying is done on a per axis basis, thus a subsection with the minimum of the old and new shape is copied.
Resize without argument is equal to resize(IPosition()).
It is important to note that if multiple Array objects reference the same data storage, this Array object still references the same data storage as the other Array objects if the shape does not change. Otherwise this Array object references newly allocated storage, while the other Array objects still reference the existing data storage.
If you want to be sure that the data storage of this Array object is not referenced by other Array objects, the function unique should be called first.
