DimensionMismatchException Class

Represents an exception that is thrown when the dimensions of Matrix or Vector objects are not compatible for the requested operation.

For a list of all members of this type, see DimensionMismatchException Members.

Remarks

There are many reasons why a DimensionMismatchException may be thrown. In every case, the dimensions of some or all of the Vector or Matrix arguments involved in an operation are not compatible. Some examples of requirements that may be violated, resulting in a DimensionMismatchException, are:

• A method requires a Matrix to be square. The matrix that was supplied is rectangular.
• An operation on two Vector objects requires that the two vectors have the same length. Most operations on vectors have this requirement.
• A multiplication of a Matrix and a Vector requires that either the number of rows or the number of columns in the matrix equals the length of the vector.
• A multiplication of two matrices requires that the 'inner' dimensions are the same.

A number of properties give more information about the cause of the exception: FirstDimensionType, FirstParameterName, SecondDimensionType and SecondParameterName.

You can avoid this exception by verifying that the dimensions of the objects (RowCount, ColumnCount and/or Length) are compatible for the operation you want to perform.
