You are to write three separate functions to modularise the process of reading any data from an excel

spreadsheet into a nested structure array. The main function MUST call GetFileName and GetData in its

execution. The functions, inputs and outputs are defined as follows.

Sub$-$function $1$: GetFileName

This function retrieves the file names of a single excel file that contains the KeyWord, from your current

working directory. For example the KeyWord may be $$Drone$$

$[$FileName$]=$ GetFileName $($KeyWord$)$

The function uses as input:

$1.$ KeyWord, which is the file name prefix that will be used to distinguish the relevant file that you

should use from the other files in your working directory.

The function must produce as output:

$1.$ FileName, a $1\backslash$times $1$ cell array containing the full file name of the file that contains your desired

prefix and extension.

Please note, the KeyWord may change. Hardcoding will be penalised.

You may use the prefix $.$xlsx to indicate that all data files that are Microsoft Excel Open XML Spreadsheets.

The data files follow rigid file type, file name and variable labelling conventions. The file structure and

labelling conventions are as follows:

The excel file contains only one worksheet, the worksheet, SheetName will always have a unique name where:

a$.$SheetName$$ is a worksheet that contains the multiple columns of data. Note: The number of

columns occupied with data may vary.
