IT IS PLEASANT to see a company which is not afraid to cover a specialised area in the Sinclair market. University Software produces five cassette tapes for students at A level or university standard. The programs are available for the 16K ZX-81 and the 16K Spectrum. Tape one introduces matrix operations. The second explains polynomials. It includes quadratic equations, Newton-Raphson and half-interval search methods.

Tape three deals with integration, using Simpson's and trapezoidal rules.

The fourth tape covers regression. The program can deal with up to 20 independent variables, with standard errors, and also illustrates interpolation.

Tape five concerns linear programming and is capable of handling up to 20 variables and the same number of constraints.

All programs can be bought separately, or as a package costing £30. The first three tapes cost £5.95 and the fourth and fifth £6.95. They arc available from University Software, 45C Sloane Street, London SW1X 9LU.
