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 under the GNU LGPL. It requires an
OpenStep(TM) compliant Foundation kit (such as NeXT's OPENSTEP,
GNUstep, or MacOS X. Get it from:
