These are the locations in the matrix in which the logical expression is true, in this case, any location greater than 12. Now the expressionA(A > 12) extracts the matrix elements corresponding to the nonzero values of the logical array. The output is always in the form of a column ...
Jacopo Zini2021년 4월 21일 0 링크 번역 댓글:Jacopo Zini2021년 4월 22일 Hi all, I have poltted on spectrum (x=Raman shift, Y= intesity) and I'd like to get the position of one peak in the matrix i.e.find the index of the the peak at 1400. ...
值函数(value function) Reward定义的是立即的收益,而value function定义的是长期的收益,它可以看作是累计的reward,常用v来表示。 环境模型(a model of the environment) 预测environment下一步会做出什么样的改变,从而预测agent接收到的状态或者reward是什么。 总之,强化学习作为一个序列决策(Sequential Decision Making...

How do I get index matrix for matrix of values? hi, can anyone one help me if i have matrix A i want get index matrix for matrix A A=[9 5 1 6 5 7 8 4 11] for exmple The result A_index =11 12 13 21 22 23 31 32 33...
Cross-correlate the two matrices and find the maximum absolute value of the cross-correlation. Use the position of the maximum absolute value to determine the shift in the template. Check the result against the known shift. cc = xcorr2(offsetTemplate,template); [max_cc, imax] = max(abs(cc...
第一种是Matrix Market (.mtx 格式),中间right hand side 是方程组 Ax=b 的右端项b。 第二种是 Harwell—Boeing 即(HB 格式) .rua 格式 。 注:mtx格式的矩阵就是通常的坐标存储方式,记录所有非零元的行和对应的列,而HB格式是新的存储方式,按照某种压缩原理,记录非零元,简单讲就是HB格式效率更高,同样...
FUN accepts % input X and returns a scalar function value F evaluated at X. X0 may be % a scalar, vector, or matrix. % % X = FMINCON(FUN,X0,A,B,Aeq,Beq) minimizes FUN subject to the linear % equalities Aeq*X = Beq as well as A*X <= B. (Set A=[] and B=[] if no...
binwidth = srate/fftpts; % 100 Hz sample rate/ 100 points in FFT f=[0:binwidth:srate-binwidth]; % frequency scale goes from 0 to sample rate.Since we are counting from zero, we subtract off one binwidth to get the correct number of points ...
Many of the functions that you might make use of when programming MATLAB are implemented in MATLAB syntax themselves – by professional MathWorks programmers. To look at such the contents of themean()function (which calculates the average mean value of an array), typeedit meanon the MATLAB comm...
