At least two favorable reviews have been posted lately, which I will email to interested parties. --------- WaveMetrics is proud to introduce Igor, a powerful graphing and data analysis program for the Macintosh. Igor is designed for experimentation with numeric data and production of publication quality scientific and engineering graphs. Here are some unique features of Igor. It is FAST. Graphs are updated almost instantly. Number and length of data sets are limited only by available memory. Each variable and data array can individually be single or double precision, real or complex. Imports data via text files or via the clipboard. You can also synthesize data using mathematical expressions. Graphs can contain any number of data sets, each with it's own color and line style (including true dashed lines). Graphs are printed at the highest available resolution of your printer. You can print multiple graphs per page, overlay graphs and print poster-sized graphs. Supports linear, log/log and semilog graphs with up to four axes per graph. Labels and annotation can use sub/superscripts and any combination of fonts, sizes and styles. Graphs support zooming, panning, auto and manual scaling. Each graph can have its own cursors and cursor information panel providing dynamic readout of several quantities (including delta-X and delta-Y when two cursors are in use). Tick marks are always labeled intelligently even under pathelogical conditions. Most errors encountered during the execution of a user's macro can be corrected on-the-fly. Data analyses include: manipulation of data with straightforward mathematical expressions which can draw upon more than 80 functions linear curve fitting to lines & polynomials; non-linear fits to sines, exponentials, double exponentials, Gaussians and Lorentzians. Igor can automatically provide initial coefficients for the non-linear fits. FFTs and IFFTs on real and complex data smoothing histogram generation integration and differentiation descriptive statistics searching and sorting very powerful and flexible waveform arithmetic All operations can be invoked from dialogs, from structured macros or from a command line. You can write a simple macro to load your data from a file, make a graph with styles of your choice and print the graph. Igor runs on a Mac Plus, SE, II or IIx. It requires a minimum of two floppy drives and 600K of available memory. It supports the 68881 math coprocessor, color, large screens and multiple screens. It requires version 3.2 or later of the Macintosh operating system and supports MultiFinder including background processing. Igor is available immediately from WaveMetrics. The single quantity price is $195 plus shipping. Quantity discounts and site licenses are available. For more information contact: WaveMetrics P.O.
