I\'m using Mathematica and have a set of variables (A,B,C,D,...) with properties A=(blue, big, rounded), B=(red, small, spiky), and so forth. Those properties can be common between variables. Wh开发者
How do you define a special operator in Mathematica, for example a special type of additive or multiplicative operator? I did that in the past but I can\'t recall where I put the code.
Suppose I have a nested list: {{2,0,3},{4,0,4},{0,0,9}}. I would like to change all the 0 to 0.00001, or some other small value, so that the final result is {{2,0.00001,3},{4,0.00001,4},{0.00001,0.000
I\'m trying to curve fit an arbitrary sum of distributed gaussians to a function -- each with their own set of parameters. Currently, if I want to use twenty functions, I do the following
I have a Graphics3D object. I want to export it as a bitmap, and to calculate the bitmap-pixel coordinates of certain 3D points.
I am working with Wolfram Mathematica 8 and have the following problem. I have an optimization problem under certain constraints and want to have an analytical (symbolical solution). I am maximizing f
I have two images. The first one is of background noise + content, and the second one is just of the background noise. I would like to subtrac开发者_Python百科t the second image from the first to remo
In Mathematica, I\'d like to do something along the lines of: f[Rational[a_, b_], Rational[c_, d_]] := {a+c, b+d}
I want to implement this in Mathematica: 开发者_JAVA百科I realize I can use ParametricPlot to get the lines, and then use the Mesh option to fill in the colors. Can anyone tell me what a general form
I was playing around with the Prefix and Postfix operators (@ and // respectively) and I ran into the following issue.
