How to write MATLAB code that maps a given set of three voltage gradients onto a strain field? Also Select the constant of greatest magnitude for each material to represent a single value that you will use for your instrument. In other words, ignore the tensor properties for the time being and treat B as a scalar.

Design an atomic force micrscopy head that has a maximum voltage of 400 V and which
can deform 10 cm using the material with the smallest piezoelecric constant. Assume that
deforming the x-crystals does not deform the y-crystals. Essentially you will select a length
of the crystal. The length of the crystal will be the same for all three materials.

Build a MATLAB GUI that allows the user to a) select any combination of the three materials, b) virtually move the tip of the AFM independently in x and y. c) visualize the movement of the tip of the AFM with respect to the base as a function of voltage.

Also help write a second GUI that animates the strain deformation of a cube given three
independent voltage gradients.

This sounds like a homework question and in general this newsgroup requires
people posting homework questions (or questions that sound like they're
homework, even if they're not) to show what they've done to try to solve the
problem and to ask a SPECIFIC question before the readers will offer any
suggestions. Post the code you've written to try to solve those questions
and indicate where EXACTLY you're stuck and someone may offer some
assistance.
