    Maple Plotting Multiple Functions on Maple Graphs

    Hi there I would like to plot a two/several functions using Maple on the same graph but with different intervals on the x exis. What I have at the moment is a Maple command for plotting two/several functions on the same graph with the same interval on the x exis. Thanks Amos

    Maple Why Does Maple Return Symbolic Answers When Integrating Functions?

    Hi every body I am trying to intergrate the following function using Maple: j2out(x):=c2*x*exp(int((s-vout(s))/s/vout(s),s=0.0015..x)); where vout(s)=0.07595560773650. C2 is constant but when I do, it returns a symbolic answers i.e Maple just returns the original expression without...

    MATLAB Some Matlab technical programming problem

    Sorry CEL, I meant nu not nu1. Also cc is meant to be a vector.

    MATLAB Some Matlab technical programming problem

    Thank you Trambolin for the reply. But are you implying that I should then redefine the matrix entries to be vectors?

    MATLAB Some Matlab technical programming problem

    Hi there every one I need some help with the following function: function cc = find_cc(n) global nu cc(1)=(-8.*i.*nu1-3.*n.^2-5+4.*i.*nu1.*n-4.*n)./n./(-n-2+4.*i.*nu1); cc(2)=(3.*n.^2+2.*n+4)./n./(-n-2+4.*i.*nu1); cc(3)=-(n-1).*(n+1)./n./(-n-2+4.*i.*nu1); end where \nu is...

    MATLAB Having a problem with soling a second order ODE equation using Matlab

    Hi, Michel Thanks for the replay. We derived the above equation by solving linearized Einstein equations for the Bondi-Sachs metric when the background is Schwarzschild. To do that we solved hypersurface, evolution, and contraints equations and in the end we ended up with the above equation...

    MATLAB Having a problem with soling a second order ODE equation using Matlab

    I am having a problem coding a Matlab code that solves a second ODE equation which I give below: x^3*(1-2*x*M)d^2J(x)/dx^2+2*(2*x^2+i*nu*x-7*x^3*M)*dJ(x)/dx -2*(2*x+8*M*x^2+i*nu)*J(x)=0. where M = 1 (Mass of a black hole), nu = 0.74734+0.17792*i, J is a function of x, i represents a complex...
