Hi Matlab community members,
i am using this code to fill or label as '1' in the matrix with respect to width size as 10
So if the ii and jj indexes are present, the number 1 will be filled. its good.
But i need help how to deal that matrix where only zeros are present.
i want to fill that grid only as '0'. I tried to use if else statement but could not succed.
Will be very thankful for guidance and help.
regards,
xx = -40:10:40;
yy = -40:10:40;
% Size_x=numel(xx);
% Size_z =numel(zz);
% Result_matrix = zeros(Size_x,Size_z);
Boundary_x = 10*floor(Slice_x/10);
Boundary_y = 10*floor(Slice_y/10);
[~,ii]=ismember(Boundary_x,xx);
[~,jj] = ismember(Boundary_y,yy);
Result_matrix(sub2ind([Size_x,Size_y],ii,jj))=1;
dlmwrite('Matrix_Boundary_fills_1s_only.txt',Result_matrix
