MATLAB: How to write something to run this function

crchexinputMATLABmatlab function

I am relativitly new to MATLAB. Most of my new learnings have been learning how to write and run BASIC Functions. I downloaded this CRC32 bit function from File Exchange and I am having a hard time to run/callout the function.
I am trying to enter a HEX number and return the CRC Calculation in HEX.'
I am trying to calculate the CRC for something like "00060D00"
function crc = crc32(data)
%crc32   Computes the CRC-32 checksum value of a byte vector.
%--------------------------------------------------------------------------
%   CRC = crc32(DATA) computes the CRC-32 checksum value of the data stored
%   in vector DATA. The elements of DATA are interpreted as unsigned bytes
%   (uint8). The result is an unsigned 32-bit integer (uint32). Polynomial
%   bit positions have been reversed, and the algorithm modified, in order
%   to improve performance.
%   Version:    1.00
%   Programmer: Costas Vlachos
%   Date:       23-Dec-2014
% Initialize variables
crc  = uint32(hex2dec('FFFFFFFF'));
poly = uint32(hex2dec('EDB88320'));
data = uint8(data);
% Compute CRC-32 value
for i = 1:length(data)
    crc = bitxor(crc,uint32(data(i)));
    for j = 1:8
        mask = bitcmp(bitand(crc,uint32(1)));
        if mask == intmax('uint32'), mask = 0; else mask = mask+1; end
        crc = bitxor(bitshift(crc,-1),bitand(poly,mask));
    end
end
crc = bitcmp(crc);
I saved it a new folder and path with nothing in there except this function (crc32.m)
When I click "Run" directly in the "Script" Tab/Window, this is what I get in the Command Window:
>> crc32
Not enough input arguments.
Error in crc32 (line 16)
data = uint8(data);
And takes me to the "Run" and shows this:
Can some explain this to me as well as how to call and use this function? Write a code? What I need to do to run and execute this funtion? How to enter?

Best Answer

crc32(data);
%......^??
You have to pass the input arguments (data) as mentioned in the function code. e.g. 
>>data=[1:18]; % Pass the appropriate data type as per function defined??
>>crc32(data)
