Hello
I am new to the MATLAB and I need help
I want to generate a matrix with 2 columns and changeable number of rows according to user input. each number in the matrix will be more than the previous one with a certain number define by user. (in the example below I used 0.4)
here is the output that I am trying to obtain
[ 0 0
0.4 0
0.8 0
1.2 0
0 0.4
0.4 0.4
0.8 0.4
1.2 0.4
0 0.8
0.4 0.8
0.8 0.8
1.2 0.8
0 1.2
0.4 1.2
0.8 1.2
1.2 1.2 ]
any suggestions ??

step = 0.4;
v = 0 :step : 3*step;
[X,Y] = meshgrid(v);
OutMg = [Y(:), X(:)];
step = 0.4;
v = 0 :step : 3*step;
[X,Y] = ndgrid(v);
OutND = [X(:), Y(:)];
Choose the function that most closely approximates what youwant to do. Here, they both produce the same result.

Call the meshgrid function and reshape the outputs from meshgrid into column vectors.

[C1, C2] = ndgrid((0:num_increments-1) * increment_value);
output = [C1(:), C2(:)];
