I am looking for unix based math analysis tools that can provide the following functions: o Generation of automatic line graphs, scatter plots, and polar plots. I am looking for such features as the super- position of plots, auto-scaling and data fitting, displaying of data in either a linear or logarithmic fashion along either axis, and driver support for digital plotter and high resolution graphics. o A Curve Fitting Toolbox consisting of least squares polynomials, multi-linear regressions, parametric and non-linear curve fitting, weighted least squares, exponential and logarithmic fits, orthogonal polynomials, and cross-correlation. o A Digital Signal Processing (DSP) Toolbox consisting of data smoothing, differentiation and integration, peak detection, convolutions, filtering and Fast Fourier Transform (FFT) packages. o A library of mathematical, graphics, and statistical functions consisting of basic mathematical operators, descriptive statistics, and array manipulation and control. I would appreciate any information on commercial off-the-shelf products supporting such functions. Jospeh Kim Hughes Aircraft Company
