MATLAB: I want to plot a 15 points randomly in square of dimensions (100*100) such that minimum distance between every point should 5. please help.

clc;
clear all;
n=15;
X=randi([1,100],1,10);
Y=randi([1,100],1,10);
L=[0,100,100,0,0];
B=[0,0,100,100,0];
plot(L,B,'k','LineWidth',8);
plot(X,Y,'k','*k');

MATLAB: Uniformly distributed 10 number between [-100,100]

If you want them to be uniformly spaced then use linspace

x = linspace(-100, 100, 10);

If you want them to be uniformlay distributed random numbers then

xLow = -100;
xHigh = 100;
x = rand(1,10);
x = (xHigh - xLow)*x + xLow;

MATLAB: Eigen value of 100*100 Symbolic Matrix

Hi Patel,

Matrix computations which involvs many symbolic variables can be slow. In your case we have 100x100 symbolic matrix which makes the speed slower. To increase the computational speed, you can reduce the number of symbolic variables by substituting the given values for some variables. Also the “symengine error” is arising because of the similar reason, it is taking more time to evaluate the eigenvalue, you can check this by reducing the matrix size and see weather the same error arise.

I hope this helps you.
