    Description

    The Numerical Information Manipulation System extends the versatility provided by word processing systems for textual data manipulation to mathematical or statistical data in numeric matrix form. Numeric data, stored and processed in the matrix form, may be manipulated in a wide variety of ways. The system allows operations on single elements, entire rows, or columns, or on entire data matrices. Data elements may be transformed by logarithmic power, exponential, and other operations. When data sets are treated as a single matrix unit, they may be added, subtracted, multiplied, inverted, and separated or merged in any desired configuration.
