Maxima is an opensource Computer Algebra System based on the legendary Macsyma.

Maxima can manipulate a wide range of symbolic and numerical expressions. The system handles differentiation, integration, Taylor series, Laplace transforms, ordinary differential equations, systems of linear equations, polynomials, and sets, lists, vectors, matrices, and tensors.

Maxima yields high precision numeric results by using exact fractions, arbitrary precision integers, and variable precision floating point numbers. Maxima can plot functions and data in two and three dimensions.

How to make Maxima display more digits

How do you make Maxima print out all the digits it possibly can? For example I entered 256^(256); and maxima returned 323170060713110073007148766886[557 digits]952148193555853611059596230656. I want it to print all the 557 digits in between, how do…

maxima: use function as function argument

Like the title says, I want to use a function as a function argument. Intuitive I tried something like: a(t,c) := t+c; b(R_11, R_12, R_13, d_1x, d_1y, d_1z) := R_11*d_1x + R_12*d_1y + R_13*d_1z; f( a(t,c), b(R_11, R_12, R_13, d_1x, d_1y, d_1z),…

how to integrate / link R and Computer Algebra Systems (CAS)

I'm looking for a possibility to use different 'higher' math operations in combination with R. A link or integration between R and a CAS would be the perfect solution. Which integration of R and other (math & statistic related) systems or vice verse…

Maxima: what does Maxima call an "array"?

I am a bit confused ; I noticed that if I do : a[sqrt(2)] : 1; arrays; I would get : [a] So a is an array for Maxima… yet sqrt(2) is an irrational number. I use to think of an array as a collection of items sorted by indices, where those indices…

Maxima: how to plot a 2D and 3D vector?

What is the simplest way to plot and 2D and 3D vectors using wxMaxima? I have searched around, but all the solutions seem too complicated just for a single plot of simple vector, is that possible? I would like to see 3 vectors at the same time in a…

Maxima: display list vertically

By default, Maxima displays lists "horizontally" : (%i1) myList : [1,3,7]$ myList; (%o1) [1,3,7] I am working with lists containing very few atoms, but each atom takes up a lot of space when displayed. Therefore it would be more convenient…

Maxima - differentiating a piecewise function

Suppose you have a function defined by intervals, such as f(x):=block(if x<0 then x^2 else x^3); When we differentiate it with diff(f(x),x); we get d/dx (if x<0 then x^2 else x^3) whereas I'd like to get (if x<0 then 2*x else 3*x^2) Is there a…
