Create a character array \'pats\' with the following entries: , \'PHT45\', \'PHT

Question

Create a character array 'pats' with the following entries: , 'PHT45', 'PHT2', 'PHT273', ‘PHT61', 'PHT14', 'PHT423','PHT195' (these are anonymous patient IDs for a clinical study). Use two different methods to create this array.

Create the character string statement = 'Where is patient PHT14?'. Use strfind (read about this in the help) and the array pats you just created to locate the first occurrence of pats(5,1:5) in the string.

Create an anonymous function for [cos(3x) exp(-x/6)]. Create a range vector (any name you chose) as 0:0.1:10. Use the anonymous function in a composed plot statement to plot the function value at each value of the range vector against the range vector. Provide the plot in addition to your command line statements.
