Hello, I have a problem with the task, if someone could direct me / tell me how to do it
I have to do:
Create a 100-element vector of random positive numbers and then write it as a matrix with the number of rows equal to the number of unique numbers in the vector and 100 columns
and then to each element of the original vector encode its value as 1 in the field with index equal to the value of this element (one-hot encoding).
Thanks in advance!!!

a=randi(100,1,100);
b=unique(a);
c=zeros(length(b),100);
for k=1:length(b)
c(k,:)=a==b(k);
end
