Using the C++ Math Library

Assigning Values to Elements in a Field

You can also modify array data contained in a structure field. You must pass the field name to mwArray::field() and the type of indexing to perform on the contained array. For example, this code replaces a 3-by-3 subarray of the image data of the ninth image, with the data in the 3-by-3 array x. You might do this as part of some image processing operation.

images(9).field("image")(colon(1,3),colon(2,4)) = x;

images(9).image(1:3,2:4) = x performs the same operation in MATLAB.
