Copies the value of the expression other into *this

*this might be resized to match the dimensions of other. If *this was a null matrix (not already initialized), it will be initialized.
Note that copying a row-vector into a vector (and conversely) is allowed. The resizing, if any, is then done in the appropriate way so that row-vectors remain row-vectors and vectors remain vectors.

Resizes the matrix to rows x cols while leaving old values untouched.
The method is intended for matrices of dynamic size. If you only want to change the number of rows and/or of columns, you can use conservativeResize(NoChange_t, Index) or conservativeResize(Index, NoChange_t).
Matrices are resized relative to the top-left element. In case values need to be appended to the matrix they will be uninitialized.

Copies the generic expression other into *this.
The expression must provide a (templated) evalTo(Derived& dst) const function which does the actual job. In practice, this allows any user to write its own special matrix without having to modify MatrixBase

This is a special case of the templated operator=.
Its purpose is to prevent a default operator= from hiding the templated operator=.

Resizes *this
to a rows x cols matrix.
This method is intended for dynamic-size matrices, although it is legal to call it on any matrix as long as fixed dimensions are left unchanged. If you only want to change the number of rows and/or of columns, you can use resize(NoChange_t, Index), resize(Index, NoChange_t).
If the current number of coefficients of *this
exactly matches the product rows * cols, then no memory allocation is performed and the current values are left unchanged. In all other cases, including shrinking, the data is reallocated and all previous values are lost.
Example:
Output:
|
inline |
Resizes the matrix, changing only the number of rows.
For the parameter of type NoChange_t, just pass the special value NoChange
as in the example below.
Example:
Output:

EIGEN_STRONG_INLINE Derived & Eigen::PlainObjectBase< Derived >::setRandom | ( | Index | newSize | ) |
Resizes to the given newSize, and sets all coefficients in this expression to random values.

Example:
Output:
EIGEN_STRONG_INLINE Derived & Eigen::PlainObjectBase< Derived >::setRandom | ( | NoChange_t | , |
Index | cols | ||
) |
Resizes to the given size, changing only the number of columns, and sets all coefficients in this expression to random values.
For the parameter of type NoChange_t, just pass the special value NoChange
.
