How to use while loop for Matrix operation using Backslash

I have matrix D as N*M and matrix T as a M*1 now my result is X matrix which is obtained using X = D\T basically to solver system of linear equation.

Now I want to use while loop for this operation as I want the values of X which is also M*1 matrix under a certain tolerance.

Any guidence will be helpful.

Not clear what you mean.

Perhaps —

D = randn(10,4);
T = randn(10,1);
v1 = ones(size(T));

for k = 1:size(D,2)
    X(:,k) = [D(:,k) v1] \ T;
    vr(:,k) = linspace(min(D(:,k)), max(D(:,k)), numel(T)).';
    LR(:,k) = [vr(:,k) v1] * X(:,k);
end

NrSP = size(D,2);                                               % Number Of subplots  
figure
for k = 1:NrSP
    subplot(NrSP/2,2,k)
    plot(D(:,k), T, '.')
    hold on
    plot(vr(:,k), LR(:,k), '-r')
    hold off
    grid
    title(sprintf('Column %2d',k))
end
