- Field Detail
  - _nRows
```
protected int _nRows
```
    The number of rows of the matrix construction.
  - _nColumns
```
protected int _nColumns
```
    The number of columns of the matrix construction.
  - _form
```
protected int _form
```
    The form of the matrix construction. _form is 1 when the matrix construction gives all elements. _form is 2 when using regularly spaced vector construction.
