This document discusses solving a plane stress problem in MATLAB and provides the code to do so. It asks if the problem can be solved in MATLAB and the code sent. It then provides: 1) A plane stress problem with stress components σx, σy, and τ to calculate principal axes, stresses, and maximum shearing stresses. 2) A MATLAB code using imrotate to rotate an image A by an angle around its center point. 3) It describes the imrotate function and how it can rotate images with different interpolation methods and bounding box specifications.

Solution
B = imrotate(A,angle)
B = imrotate(A,angle,method)
B = imrotate(A,angle,method,bbox)
gpuarrayB = imrotate(gpuarrayA,method)
Description
B = imrotate(A,angle) rotates image A by angle degrees in a counterclockwise direction around
its center point. To rotate the image clockwise, specify a negative value for angle. imrotate
makes the output image B large enough to contain the entire rotated image. imrotate uses nearest
neighbor interpolation, setting the values of pixels in B that are outside the rotated image to 0
(zero).
B = imrotate(A,angle,method) rotates image A, using the interpolation method specified by
method.
B = imrotate(A,angle,method,bbox) rotates image A, where bbox specifies the size of the
returned image. bbox is a text string that can have one of the following values.

2. gpuarrayB = imrotate(gpuarrayA,method) perform operation on a graphics processing unit
(GPU), where gpuarrayA is a gpuArray object that contains a grayscale or binary image, and the
output image is a gpuArray object. This syntax requires the Parallel Computing Toolbox
