# The description about the az of view is wrong.

The decription about the az are as follows:
```
az Azimuth
number
Azimuth, specified as an angle in degrees from the negative y-axis. Increasing this angle corresponds to counterclockwise rotation about the z-axis when viewing the x-y plane from above.
```
I think the word "counterclockwise" is wrong. It should be "clockwise". The code can prove that.
az=45;
[X,Y,Z] = peaks;
figure
surf(X,Y,Z)
xlabel('X')
ylabel('Y')
zlabel('Z')
view(az,45)
az=60;
figure
surf(X,Y,Z)
xlabel('X')
ylabel('Y')
zlabel('Z')
view(az,45)

I guess this line in documentation is about the rotation of observer around the +z-axis. If you look at the explanation about the line of sight here: https://www.mathworks.com/help/matlab/ref/view.html#mw_a674278c-855a-4302-98e4-fc13c181cfd8, you can see that when the observer's line of sight rotates counterclockwise, the axis appear to have rotated clockwise.

Good explanation. The subject of counterclockwise rotation about the z-axis is the line of sight, not the x-y plane. Thanks!
