Question

Create an array of two structures that represents two image and their sizes. my_images (1). imagename = 'Image 1'; my_images (1). width = 256; my_images (1). height = 256; my_images (2). imagename - 'Image 2'; my_image (2).width = 128; my_images (2) height = 128; How to view details about the structure? my_images(1) How to display details about the contents of a field? my_images (2) image name Some specific information about the structure: mum_of_image = prod (size(my_images)) fieldnames (my_images) What does the fieldnames function do? What does it mean when the result from the function isstruct is 1? What does it mean when it is 0? Use the help system to determine what function can be used to delete a field from a structure

Explanation / Answer

Fieldnames defines names of the structure or public fields of an object.

names = fieldnames(x):

Here the fieldnames function returns a cell array of strings containing the structure field names associated with the structure x.

Isstruct

This function determines whether input is structure array.

If isstruct(my_images) returns logical 1 (true) then my_images is a MATLAB structure array.

If isstruct(my_images) returns logical0 (false) then my_images is not a MATLAB structure array.
