Matrix-matrix-2018 June 9Today is a pity, not too much to learn R language (mainly because to listen to party lecture, learned the party important speech, so no reading), so today summed up a matrix bar. But more study.First of all, a little review of yesterday's factor, the first thing to remember is mode () look at each element, class () see what is the whole,
$f_n$And because matrix multiplication satisfies the binding law, the idea of a fast power can still be used here, so we can use the fast power of thinking, in a very short time to find out the $b^{n-1}$What advantages does this algorithm have?Of course there are, for example, I asked you to ask for the $10^{15}$ of the Fibonacci sequence.At this point the matrix can be quickly $log 10^{15} \ast$
The color matrix M is a matrix of 5*4, and the color matrix m in android is stored in a one-dimensional array m=[a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t] way.Each line of the matrix is:R[a b c D E]G[f G h i j]B[k l m N O]A[p Q R S t]The RGBA value of the image is stored in a 5*1 color component

Snake ($row = 5, $col = 5) { //result set $res = Array (); Initial value $start = 1; The number of currently traversed layers $flag = intval (($row + 1)/2); for ($i = 1; $i
The second way of thinking
This way of thinking is similar to the first, but through a while all traversal, and then through a flag bit up to the left to judge and modify the current direction, through the if in the while to judge the flag bit, this does not post code
The third way of thinking
Using an iterator to c
