There are three assignments this week. It takes about one day to write General programs.Experience
The Set () and {} results are the same and can be used universally. The latter can be used.

This section describes matrix operations. It is worth noting that the meaning of left multiplication and right multiplication sparse matrix, and the inverse method of

improved instruction scheduling on this code.
In the macro, adjacent multiply instructions write to the same register, so the neon pipeline must wait for each multiply to complete before it can start the next instruction.
If we take the instructions out of the macro and rearrange them, we can separate those that are dependent using other instructions that are not dependent. these instructions can be issued whilst the others complete in the background. in this case, we rearrangeThe code to space

Coding the matrix: Linear Algebra through
Computer Science Applications
This assignment is not difficult. The first job hw1 is fine, and the second job can all be completed using comprehension. However, be careful about the returned values and have a deep understanding of the concept of Vector in this course. The third task is not difficult, but it is wrong when you are not careful. One reason is that grade

Coding the matrix: Linear Algebra
Through Computer Science Applications
This is a course for implementing matrix operations using python. For the first assignment, I felt that python was greatly improved and various data types were used.The Code is as follows:
## Task 1minutes_in_week = 60*24*7## Task 2remainder_without_mod = 2304811-2304811//47*47## Task 3divis

Matrix: Linear Algebra through Computer Science Applications
This week, there are only a few jobs. Only one programming task, hw2. the job is relatively simple. If you have studied matrix algebra in college, there is basically no problem, however, it should be noted that the method of span of base 2 is used.
In the base 2 space, take any number of base vec

sparse storage matrix is only stored in different ways. It has the same operation rules as normal matrices and can be directly involved in operations. Therefore, full matrix operations and functions in Matlab can also be used in sparse matrices. Whether the result is a sparse matrix or a full matrix depends on the ope

We know that the encoding method should be declared in the header file of Python source code. If you don't just use ASCII code, many people may write a little different:
# Coding = UTF-8
# Coding: UTF-8
#-*-Coding: UTF-8 -*-
So how can we effectively write data? What advantages are ineffective?

1. Prediction code
CompressionAlgorithmThe essence is to remove redundancy between signals. What is signal redundancy? The correlation between signals is redundancy. human hearing or visual systems that do not feel or mask can also be used as redundant components. Today we will talk about the concept of predictive coding, which is a very intuitive and simple method. It is intuitive. Taking an image as an example, There Are similarity and correlation

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,

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

Sparse Matrix and sparse matrix compression storage, Matrix
The unprocessed sparse matrix is actually a special two-dimensional array. Most elements in the array are 0 or other types of illegal values, and there are only a few non-zero elements.
To achieve compression and storage, only non-zero elements of the sparse

The role of a model view projection matrix is to transform vertices from a local coordinate system into a canonical cube (Canonical view volnme). In summary, the model view projection matrix = projection matrix x view matrix X model matrix, the model

At first, I thought this question was a raw question about the rapid power of the matrix,
Later it was found that it would time out, and the super would exceed M = C ^ (N * n). This operation, and the C itself is a matrix of N * n, with N at the maximum of 1000.
But here is a clever place: the source of C is actually = a * B. A is a matrix of N * k, and B is a
