NUMBERCRUNCH II is on the way!
I've been working steadily on a major upgrade to NumberCrunch, which I hope to have done and ready to sell for about $50 or so this summer. (By the way, if anyone out there has a suggestion for a good way for me to market this, I'm all ears...)
NumberCrunch II already has (as of 3/90)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
• arrays, for example
j={2,5,7}
x = 1…10@.2 which sets x = {1, 1.2, 1.4, ... 10}
y = sin(x)/x which takes sin(x)/x for each value of x
y[j] = {y[2], y[5], y[7]}
• Pascal-like programs, for example
Function Integrate(theFunc, theMin, theMax, dx)
var j
begin
j = theMin…theMax@dx # sets j = to an array
Integrate = dx* sum( theFunc(j) )
end
( then if f(x) = x^2, Integrate(f,1,2,.01) gives .01*[ 1^2+ 1.01^2 + 1.02^2 +...+ 2^2 ] = 2.35835 )
• complex numbers and functions (sin, cos, exp, etc.) of complex arguments,
• strings (so that the pascal-like programs can format their output),
• multiple files open and multiple windows per file in the application,
• externally compiled Xcod resources to perform specialized functions (like fast-fourer transforms,)
• command completion,
and it will have :
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
• matrices and higher dimension arrays,
• units (kg, m, sec, etc.)
• spread-sheet like entry of matrices and arrays, or entry from a data file
• better graphics, including vectors and contour plots.
So keep your eyes out for it. It'll be worth waiting for. (I hope).
