Description
The programme examines how some matrices can be shown to represent dilations in skew directions. The importance of this result is then demonstrated by showing how it can be used for calculating pow...ers of matrices.

Footage description: Building on the results of the previous programme, that a dilation in skew directions can be represented as a matrix (...). John Mason and Norman Gowar develop a technique to demonstrate which general matrices represent a dilation in skew directions. John now demonstrates how this result can be used to calculate powers of matrices. As a practical example of the importance of this result, Norman Gowar uses it to solve a weather forecasting model, used earlier in the course work.
