There are many reasons why a DimensionMismatchException may be thrown. In every case, the dimensions of some or all of the Vector<T> or Matrix<T> 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<T> to be square. The matrix that was supplied is rectangular.
• An operation on two Vector<T> objects requires that the two vectors have the same length. Most operations on vectors have this requirement.
• A multiplication of a Matrix<T> and a Vector<T> 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.
