I have 3D plot as shown in the image below.
I added the 3 axes with black color. I do not want the axes to be shown at the bottom and on the side like it is plotted by default. I wish to force them somehow to be intersect at (0,0,0) and to be shown as the image above and I have some trouble doing that.
I tried the command:
set(gca, 'XAxisLocation', 'origin', 'YAxisLocation', 'origin')
but did not work.
Is there a way to do that?

Unfortunately, the XAxisLocation and YAxisLocation properties only work for 2D axes.
Which means your only option is to draw those lines manually.
If you are OK with no ticks or tick labels, there are a few options you can consider, but my favorite is probably fplot3.
ax = axes;
xl = fplot3(ax,@(t) t, @(t) zeros(size(t)), @(t) zeros(size(t)),'SeriesIndex','none');
yl = fplot3(ax,@(t) zeros(size(t)), @(t) t, @(t) zeros(size(t)),'SeriesIndex','none');
zl = fplot3(ax,@(t) zeros(size(t)), @(t) zeros(size(t)), @(t) t,'SeriesIndex','none');
ax.XAxis.Visible = 'off';
ax.YAxis.Visible = 'off';
ax.ZAxis.Visible = 'off';
