Problems: Write pseudocode and generate a flow chart that will take as input a temperature in Fahrenheit, Celsius, or Kelvin and then print out the values of the input in all three scales. 1. Use the lookfor command in MATLAB to determine the MATLAB command necessary to read data from a file. 2. Using the help command in MATLAB, provide a definition of the floor command and list three different related commands. How does this function differ from round? 3. Given the length of the two bases (a, b) and height (h) of the trapezoid, the centroid of the trapezoid measured from the longest base b can be calculated using the formula 4. 1 2a b 3 a+ b The following program should calculate the centroid of a trapezoid measured from the longest base, given the length of the two bases and the height of the trapezoid. However, the MATLAB code contains several errors. Identify the errors in the code, and then fix the code so that it correctly calculates the centroid of the trapezoid. Run the corrected code in MATLAB what is side_e 3.5; 5.12 -side b: %height 3.1; centroid1/3 2 side_e + side b / side_ +side b height
