Computing surface area of a spherical patch

By using surf2patch(sphere(),'triangle'), the spherical coordinates of sphere are converted into triangular patches.

Is there any way of calculating the surface area of each one of these patches?

I can iterate through each patch, and obtain the cartesian coordinates of each of the vertices that form the patch, but not sure about the math part.

Thanks

This means that your triangles(polygones) are already in cartesian coordinates. I will suggest you to use the basic polygone command i.e. A = polyarea(X,Y). By this way you can iterate through all of your triangles and calculate the area of it.

Look at this mathworks.com page for more help.
