for i=1:length(X)
x=find(Matrix(X(i):1,i)<100,1,'first')'; %
X100(i)=x;
end
Unable to perform assignment because the left and right sides have a different number of elements.
Error in MatrixRead (line 16)
X100(i)=x;
I need to find the element less than 100 in reverse order.
help fix this error
X is the item number is greater than 120 (practically I need to get the value 21)
