I can change it in the following menu, but need to write a line of code, as I need to execute the section multiple ...Description example axis (limits) specifies the limits for the current axes. Specify the limits as vector of four, six, or eight elements. example axis style uses a predefined style to set the limits and scaling. For example, specify the style as equal to use equal data unit lengths along each axis. example For code generation, you can load the network by using the syntax net = alexnet or by passing the alexnet function to coder.loadDeepLearningNetwork (MATLAB Coder). For example: net = coder.loadDeepLearningNetwork('alexnet'). For more information, see Load Pretrained Networks for Code Generation (MATLAB Coder).When the data aspect ratio mode is auto, MATLAB adjusts the data aspect ratio so that each axis spans the space available in the Figure window. If you are displaying a representation of a real-life object, you should set the data aspect ratio to [1 1 1] to produce the correct proportions.The default output figure size is 8 inches wide by 6 inches high, which maintains the aspect ratio (width to height) of the MATLAB figure window. The figure's default position is centered both horizontally and vertically when printed to a paper size of 8.5-by-11 inches. You can change the size and position of the figure: Both matrices have the same rows and columns. I would like to know how I can 'reshape' both of them in the subplot so that they share the same original aspect ratio. Currently only the image drawn with imshow has the right aspect ratio. Theme.
