MathArray: Class library for mathematical manipulation of matrices MathArray is a general library of classes for performing mathematical operations on arrays (vectors, matrices, etc) of values. It can operate on any standard 'C' number type plus numbers of complex type. MathArray is implemented using a "class cluster" concept, allowing one to perform mathematical calculations on a number without necessarily being aware of what type (class) of number is being operated on. MathArray knows implicitly what types of operations can be performed on what types of numbers and will automatically cast itself to the correct number type representation to handle the specific operation. Standard operations include addition, scalar and matrix multiplication and logical operations. Mathematical operations in the standard C math library are also supported, as well as user-defined functions. MathArray also supports the NSDecimal type on systems that have this Foundation extension. MathArray also does much more. Arrays can be manipulated, transposed and concatenated. One can extract subarrays or include subarrays within larger arrays. What would you expect to pay for all this? Nothing, you say? Well wait, there's more. If you ftp now, you get the following extra classes at no extra charge: MaskedException - extends NSException to allow for special processing for debugging, exception handler objects, and other deviant behavior. MANumber,NSNumber(extras) - Adds complex number capability, protocols. MAValueData - Like NSData only it knows what type of data it stores and can access values appropriately. libMathArray is distributed absolutely free. It requires an OpenStep(TM) compliant Foundation kit (such as NeXT's OPENSTEP, Rhapsody, or GNUs gstep-base) or the NeXT Foundation kit (with EOF or NeXT release 3.3).
