How to plot 3D bar graph?

I've searched but can't find the solution on how to plot the following as a 3D graph. I have a matrix of x,y,z values, e.g.:

I want to generate a 3D plot in all 3 dimensions, with y as the height of the bar and z as the width, such as the following (not drawn to scale...I just kluged it together in powerpoint):

How do I do this? none of the following worked:

bar3(x,y,z)
bar3(z)
bar3(x,y)
bar3(y,z)

You can find the details in the documentation here:-

nah, tried that. I can't find any answer on that page

You can use this custom function

scatterbar3(x,y,z,0.5)
grid on

For example

x=1:10;
y=2:2:20;
z=3:3:30;
scatterbar3(x,y,z,0.5)
grid on

Thanks, Kalyan! Close, but no banana. For instance, for the following matrix:

1 1.00 3.43

2 1.00 3.24

3 1.00 3.20

4 0.91 3.15

5 0.69 3.07

6 1.00 2.82

7 1.00 2.76

8 1.00 2.62

9 1.00 2.61

10 0.68 2.55

I ran the following:

x=matrix(:,1);
y=matrix(:,2);
z=matrix(:,3);
scatterbar3(x,y,z,1)

I get this fig (ignore the colors, I'll fix that later):

The z dimension (0.0 to 3.0) is accurate (the height of each bar), and the x sequence (1 to 10) is shown correctly, but the widths of the bars, y, are all fixed (=1). I need the "base" of all the bars to start at y=0 and the bar's width extend up to the corresponding value of y for each entry. In short, the width should = y, not a constant.

Any ideas?
