e.g. I calculate 4 combinations(i.e.nCr(10,1)=10,nCr(10,2)=45,(10,3)=120,(10,4)=210 using for loop).Can I get these four answers as four entries of a matrix?
The command I used is >> n=10;
>> for k=1:4
nchoosek(n,k)
end (which gives above four answers)
How to get these answers as a matrix of four entries?(1st answer as 1st entry, 2nd answer as second entry of the matrix and others accordingly).So that we can further work with that matrix
nchoosek can be used with vectors for input returning a matrix. Check the second example in the documentation: https://au.mathworks.com/help/matlab/ref/nchoosek.html
Maybe this helps.
You can use cellular arrays in each loop. So you can have alternative-length matrix in each loop.
Vector form:
n=10;
for k=1:4
n_choose_k(k)=nchoosek(n,k);
end
Matrix form:
for i=1:m
for j=1:n
n_choose_k(i,j)=nchoosek(i,j);
end
end
Array form:
for i=1:m
for j=1:n
n_choose_k{i,j}=nchoosek(i,j);
end
end
