Where can I find the Scilab balanc() function to calculate the similarity transform to program it in Maxima

I'm trying to program the z-transform in wxMaxima which doesn't have it programmed but not by definition but by using the Scilab approach. Scilab to calculate the z-transform first converts the transfer function to the state space, after that the…

Incorrect Results from the Solve Command in Maxima

I am trying to solve a set of two equations for two complex variables in terms of the other terms. I put the two equations in a list and tried to solve for both the variables together, but this kept giving me incorrect results. However, if I can…

When copying and pasting the output of partial derivative of a function in Maxima, the pasted text stands instead for a total derivative

When I write the expression for the partial derivative of a function, diff(f(x_1,x_2),x_1,1), for a function f created with funmake(f,[x_1,x_2]), the returned output is However, when copying and pasting the output of the partial derivative, what I…

(wx)Maxima: list factors of an integer

How can one return the factors of an integer in a list? e.g. list_factors(6); > [1,2,3,6]? Is something like this possible? I looked through the documentation but didn't find anything like this tied to "factor" or "prime".

WxMaxima: how to plot functions defined on surfaces

Is it possible to plot with WxMaxima a function defined on a surface of R^3? The outcome I would like is to see the surface (say a sphere), colored according to the values that the function takes on it. Thanks in advance.

Plotting a Graph with EzUnits

I'm trying to plot a graph of the function Fh_1, but it looks like ezunits is causing problems. I can get results from it, when I enter x-values. But plotting isn't working, not even with dimensionally(). How can I get it to work? (%i2) kill(all);…

How to solve four unknown variables with four equations, but for more complicated input?

I'm trying to solve four unknown variables x_Trag, y_Trag, x_Zug, y_Zug with four equations eqx, eqy, Py_Trag, Py_Zug. Sadly only the easy testcase is working. Here's the Wxmaxima paste: (%i1) kill(all); load(ezunits); Warning: Can set maxima's…

Convert an expression to a function

If I have a named expression, how can I convert that to a function? Here's an example: argx: 2*x; f(x) := argx; I'd like then this to be equivalent to: f(x) := 2*x But I know somehow I have to force "unquoting" or something of argx

WxMaxima solving Equation leads to complex numbers?

I'm trying to solve the equation "eq" for "mu". How do I tell maxima that I only want the positive result, is this the best way var : abs(mu), res;? But, my main problem is, that the results contains %i, where does that come from? Shouldn't it be…

Round-off to zero behavior in Maxima float coefficients

So I am working on a Maxima program that involves a bunch of iterations (the Souriau-Frame Drazin Inverse Algorithm, to be specific), each step of which yields a polynomial. I need to check and stop my iterations when the polynomial goes to zero…

Is there a way to solve this irrational equation in wxMaxima?

it seems that wxMaxima normally can't solve this simple irrational equation: 10=x-2*sqrt(x) Here's my input and output: (%i1) f1(x):= x-2*sqrt(x)$ (%i1) solve(f1(x)=10, x); (%o1) x=2sqrt(x)+10 I've also tried other ways of solving this but…

(wx)Maxima: apply scalar function to all elements of a list

Currently, if I want to apply the transformation effected by a function of a single variables f to all values in a list, I use makelist, e.g. f(x):= x^2; aList: [1,2,3,4]; f_aList: makelist(f(aList[i]), i, length(aList)); I have to do this so often…
