## How to Specify the Number of Non-zero En...

Maple

Hi,

I am using A:=LinearAlgebra:-RandomMatrix(10,10,generator=-10..10) to generate a random matrix. How may I specify that every row of A has at least three non-zero entries?

Thanks!

## Why Can't Maple Evaluate a "Simple" Anti...

Maple 2019

I am playing around with certain "simple" integrals, and came across this strange behavior in Maple. Maple is able to integrate sin(x)^(1/2)*cos(x)^3, but not sin(x)^(1/3)*cos(x)^3. Any idea why?

Why does the iscont( ) function declare that the square root function is continous over Riscont_error.mw

## How to create the set of all possible ra...

Maple 2019

I am able to generate random polynomials with non-zero coefficents, and define sets of all the positive divisors of the leading coefficient and the constant terms. My question is this, how may I apply the rational zeros theorem to generate the set of all possible rational zeros of the polynomial. I basically need to form all the possible quotients (positive and negative) with numerator in one set and denominator in the other set, ignoring duplicates. The attached worksheet has what I've done so far.rational_zeros.mw

## Generating LaTeX code for a weighted gra...

Maple 2018

I am generating a lot of random graphs in Maple, and I need to generate the LaTeX code for these graphs. It has been working very well, until now, when I got to weighted graphs. The LaTeX code does not create the weights. I know I can modify the code to add the weights, but my question is two-fold: why aren't the weights automatically generated? is it possible to have the weight automatically generated, how? Nothing in the documentation appears to address these issues.

An example of what I attempting to do is in the attached worksheet.

Thanks!
