matlab code not working

Hi there cn anyone help me with my work...i'll put the question...

the digit 0 to 9 be associated with the alphabets A to J as follows

0-j1-h2-a3-c4-e5-g6-i7-f8-b9-d

write a matlab program that prompts the user to input a seven digit telephonenumber and then displays a list of all letters that can be formed from thenumber.for example 7848979 begins :fbebdfd, fbebddf, fbebfddsupport your work with a flow chart

xfunction alpha

%First we define a matrix

a for the lettersa = ['JHACEGIFBD'];

%Input 7 digit telephone number using 'input' function and store in matrix e

for n = 1:7,

b = input('\nPlease enter a 7 digit number (after each number press enter): ');

e(n) = b;

end

%Match each number of tel no. with a letter from matrix a and store in matrix m

for n = 1:7,

h = e(n);

m(n) = a(h);

end

%Use perms function to permutate the digits in matrix m

p = perms(e)end
