Functiоn: cоmmаndCenter Input: (uint8) An MxN аrrаy оf image data to modify (struct array) 1 x K structure array containing modification data, including source image filenames, desired width/height, and placement coordinates Output: (uint8) A MxN array containing the modified image data Function Description: You are provided the image data that corresponds to a template image that is to be modified using information provided in the structure array. Each structure in the structure array contains the following fields: imagefile -- a character vector containing the name of the file containing the image data to be copied onto the template image data width -- an integer that specifies the desired target width of this image when copied onto the template image data height -- an integer that specifies the desired target height of this image when copied onto the template image data xpos -- an integer that specifies the desired target x-position of this image when copied onto the template image data - for the TOP LEFT corner of where the image should go ypos -- an integer that specifies the desired target y-position of this image when copied onto the template image data - for the TOP LEFT corner of where the image should go Notes: You are guaranteed that the template image will be large enough to accommodate the replacements You are guaranteed all replacement image files exist Be careful when thinking about x/y coordinates and width/height with respect to row/col indicies. Remember that x position & width correspond to COLUMN while y position & height correspond to ROW. Example: templateImage data (shown as image here):   replacement images:   struct array:   modifiedImage data (shown as image):   replacementData = struct('imagefile',{'exl.png','yt.png','spot.png','mat.png'}, ...                   'width',{222,360,161,271}, ...                   'height',{418,225,161,268}, ...                   'xpos',{375,948,1279,980}, ...                   'ypos',{356,50,318,492});modifiedImage = commandCenter(templateImage,replacementData);

The Fe-C binаry system hаs the fоllоwing phаse diagram:   What is the melting pоint of pure iron? What are the temperatures of the peritectic/eutectic/eutectoid reactions? For a system with 2 wt% C, write down a. The phase(s) present b. The weight fraction and composition of each phase. starting at 1500 ˚C, cooling down to 1300 °C, 1000 °C and 800 °C. 4. Your supervisor asks you to cast a FeC alloy that will have the highest solidification range, i.e. the alloy that will remain a mixture of solid & liquid over the widest temperature interval.  What composition would you choose to work with? ATTENTION: For this question, you MUST show your work in the scratch paper in order to get any credit. Even if you give the correct answer in the textbox, you will receive no credit without showing your work.
