Gaussian Grid in 2d

How to create gaussian grid around some specific point ( x0, y0) and specific sigma( standard deviation) in X-Y plane instead of regular grid point.

Hi,

As per my understanding, you want custom grid lines that follow Gaussian distribution with specified mean and variance. Refer this how grid lines position can be changed using “xtick” and “ytick”. The following code snippet is for better understanding.

figure
x1 = -50:50;
y1 = -50:50;
scatter(x1,y1)
grid on
y_std = 25; % standard deviation along Y axis
y_mean =25 ;  % mean along Y axis
y = y_std.*randn(10,1) + y_mean; % Generating Gaussian distribution with specified mean and standard deviation
x_std = 25; % standard deviation along X axis
x_mean = 25; % mean along X axis
x = x_std.*randn(10,1) + x_mean; % Generating Gaussian distribution with specified mean and standard deviation
X_values=sort(x)';
Y_values=sort(y)';
xticks(X_values);
yticks(X_values);

Refer this for more information on how to generate Gaussian distribution with specific mean and variance in Matlab.

Thank you Swetha Polemoni. It will work fine.
