Hi there,

I am calculating he rank of a matrix in Maple and I have a result. However, I want Maple to show me the intermediate steps that it used. I know that the rank function uses gaussian eliminations. Is it possible to make it display these steps?

The matrix is 8*8 so I think it is taugh to use the tutor tool.

I tried ShowSteps but it says that rank is not a valid problem.

Any ideas?

truncated normal distribution

Dear all,

I have two questions regarding truncated normal distribution.

1. Is there a convenient way in Maple to compute and plot the density function of a truncated normal distribution? I know that in Maple, after creating a random variable, I can use the function Statistics:-PDF to compute the density function, and use DensityPlot to draw the function. But for truncated distribution, I have to compute it manually by doing integration to compute the normalized...

Hi all,

Is there some way i can find the width of a plot?

I have the equation below:

Prob:=(w,T)->(B^2)*(sin(w*(T/2))^2)/((w/2)^2);

$B^2*sin(1/2*w*T)^2/w^2$

plot(Prob(w,6),wf=-3..3);

Which produces a gaussian looking plot, the plot reaches zero at some...

Hi hi,

I've been sourcing various codes to help with plotting gaussian primes. I've managed a plot of gaussian primes within a given range with no problem at all. However, I'm looking now to make a plot of all gaussian primes connected by a step k or less to help communicate the Gaussian moat problem. ( similar to figure 2 in http://mathdl.maa...

i have an image and would like to perform a canny edge detection. one of the first steps is the convolution of the image with a smoothed derivative filter, i.e. a gaussian. the problem is, that i don`t know, how to convolve my collection of discrete pixels (the image) with a 2D gaussian. how do i get an integer-valued convolution kernel that approximates a Gaussian with a variable sigma?

Solving Sparse Linear Systems in Maple

What is the largest linear system that Maple can solve? You might be surprised to find out. In this article we present strategies for solving sparse linear systems over the rationals. An example implementation is provided, but first we present a bit of background. Sparse linear systems arise naturally from problems in mathematics, science, and engineering. Typically many quantities are related, but because of an underlying structure only a small subset of the elements appear in most equations. Consider networks, finite element models, structural analysis problems, and linear programming problems.
