MATLAB

Create the following string using the colon operator, and only the letters 'A' and 'K': Letters = 'ABCDEFGHIJK' Create the following words in MATLAB using only the elements of "Letters" BAD CAB KICK CAKE Change the 5^th element of Letters to the letter X and the last element of Letters to the letter Z in one short command. (Find the concise approach.) Extract in reverse every other element of Letters in one short command. The result would be: 'ZIGXCA' Random numbers in computing would often be more accurately referred to as "pseudorandom numbers"-sequences of numbers whose properties only approximate the properties of sequences of random numbers. Put the following lines of code in your script file to create arrays of pseudorandom numbers (these will actually be the same pseudorandom numbers that someone else would get by running these same lines). rng(1); % the argument (1) is called the 'seed'; it tells the algorithm where to start A = randi(10,1,20); B = rand(8, 8); Now calculate the following: The average value of A The maximum value of A and the index at which it occurred (one command) Create an array, C, that is identical to A except that: any elements of A that are less than 7 are assigned a value of 7 in C. (See MATLAB help on max) The average of each column of B (one command for all 8 values) The sum of each row of B (one command for all 8 values) The median of the array of medians calculated for each row of B. (1 value)
