Construct in MATLAB a histogram function myhist() for integer - valued data samples. Check that it works correctly by using randomly generated test data. Check your m - file against the output of MATLAB ’ s hist () function.

Consider the following function declaration/definition (the body of the function is not shown; assume you have such function m-file available to Matlab and it is correctly constructed): function [a, b, B] = getParameters() How many input arguments does this function require? a) 3 b) none c) 2 d) 1

Finally, we will do some simple analysis – ranking of words. Write a function word_ranking(corpus, n, sort_index) which takes input parameters corpus (type list), n (type int), and sort_index (type int) and returns a list containing tuples of words and their frequencies in the top n of words. Here, corpus is a list of sentences. n is the number of ranked words to return. The resulting list should then be sorted based on the sort_index; sort_index = 0 should sort the list of tuples in ascending alphabetical order, while sort_index = 1 should sort the list of tuples by the frequencies in descending order. All other numeric values for sort_index should return an empty list (don't need to consider non-integer inputs). For example, we have: corpus = ['hi hi hi hi', 'hello hello say bye', 'bye bye']n = 3sort_index = 1   The function should return:   [('hi', 4), ('bye', 3), ('hello', 2)]   While sort_index = 0 should return:   [('bye', 3), ('hello', 2), ('hi', 4)]     You can assume n would…

make a code , if you can uses mathlab keep basic code no if or return

Write a one sentence description of this function and suggest a more descriptive name. int func1(double x) {return (int)(x + 0.5); }

Assume that the following user-defined function is available in Matlab:   function [d, e] = someFunction(a, b, c)        d = 2 * b * c;        e = 3 * d; end   If the following Matlab expression    >> [varA, varB] = someFunction(2, 3, -2);   gets executed in Command Window (and the program control flow is transferred to the someFunction function), which value gets assigned to variable a inside someFunction?     2     -2     3     No value will be assigned to that variable

Write the MATLAB commands that assign 33 and 4 to the variables a and b, respectively. Then, create a column vector W with the elements а! In(ab) Vb - a V(a + b)² – (b – a)? -a b where y! is the factorial of y, for which you should use a built-in MATLAB function, and In(x) is the natural logarithm of x. Finally, compute the average of the elements in W.
