#Day12- Matrix Pattern
Task:
Create a matrix which will produce output with following two condition:
1) The difference successive values in a row get incremented by 1 ,when the difference starts from 2 (First and second value difference).
2)Past row last value will be present row's first value .
Note: This code can be done using the in-built command. But for the challenge, I am trying to avoid those
Example
(a has 5 rows and 9 column)
a =
1 3 6 10 15 21 28 36 45
45 47 50 54 59 65 72 80 89
89 91 94 98 103 109 116 124 133
133 135 138 142 147 153 160 168 177
177 179 182 186 191 197 204 212 221
Matlab Code:
function a=rep_mat(x,y)
%
this function will produce output in a pattern where the difference
%
between number get incremented by 1 and difference starts from 2.in first
%
row last column value will be first column value of immediate next row
%examplea=rep_mat(5,9)
%a
=
% 1
3 6 10
15 21 28
36 45
% 45

k=1;
for i=1:1:x
k=k-1;
for j=1:1:y
a(i,j)=k+j;
k=k+j;
end
end
Sample Input and Output
a=rep_mat(3,9)
a =
1 3 6 10 15 21 28 36 45
45 47 50 54 59 65 72 80 89
89 91 94 98 103 109 116 124 133
>> a=rep_mat(10,12)
a =
1 3 6 10 15 21 28 36 45 55 66 78
