Method Detail

set

void set(int i,
         int j,
         double value)

Sets a single element of this matrix.

Parameters:

i - element row index

j - element column index

value - element value

set

void set(Vector v)

Sets the size and values of this matrix to correspond to those of vector object.

Parameters:

v - vector whose size and values are copied

Throws:

ImproperSizeException - if this matrix cannot be resized to correspond to the dimensions of the vector

set

void set(double[] values)

Sets the elements of this matrix from an array of doubles. The elements in the array should be stored using row-major order, so that element (i,j) is stored at location i*colSize()+j.

Parameters:

values - array from which values are copied

setSubMatrix

void setSubMatrix(int baseRow,
                  int baseCol,
                  Matrix Msrc)
           throws ImproperSizeException

Sets a submatrix of this matrix object. The first row and column of the submatrix are given by baseRow and baseCol, and the new values are given by the matrix object Msrc. The size of the submatrix is determined by the dimensions of Msrc.

Parameters:

baseRow - index of the first row of the submatrix

baseCol - index of the first column of the submatrix

Msrc - new values for the submatrix.

Throws:

ImproperSizeException - if baseRow or baseCol are negative, or if the submatrix exceeds the current matrix bounds

setColumn

void setColumn(int j,
               double[] values)

Sets a column of this matrix from an array of doubles.

Parameters:

j - column index

values - array from which column values are copied

setRow

void setRow(int i,
            double[] values)

Set a row of this matrix from an array of doubles.

Parameters:

i - row index

values - array from which the row is copied

setColumn

void setColumn(int j,
               Vector v)

Sets a column of this matrix from a Vector.

Parameters:

j - column index

v - vector from which the column is copied

Throws:

ImproperSizeException - vector's size not equal to the number of matrix rows

setRow

void setRow(int i,
            Vector v)

Sets a row of this matrix from a Vector.

Parameters:

i - row index

v - vector from which the row is copied

Throws:

ImproperSizeException - vector's size not equal to the number of matrix columns
