Z= peaks(n)returns the peaks function evaluated over ann-by-ngrid. If you specifynas a vector of length k, MATLAB®evaluates the function over a k-by-k grid. example Z= peaks(Xm,Ym)returns the peaks function evaluated at the points specified byXmandYm. The sizes ofXmandYmmust be th...
本节将介绍一些Matlab R2011a中与图像处理密切相关的数据结构及基本操作,如基本文件操作、变量使用、程序流程控制、打开和关闭图像以及图像格式转换和存储方式等。这些都是后续将要学习的图像处理算法的基础。2.1.1 Matlab软件环境1.软件界面图2.1所示是运行于32-bit Windows操作系统上的Matlab R2011a界面。软件主界面...
求以下函数的原函数，谢谢！ f(x)=A/(B+x)^2 （-A)/(B+X)Matlab的命令中有求一个多元函数的黑塞矩阵的命令吗？有的话是什么 ？ hess The function hess has a new syntax of the form [AA,BB,Q,Z] = hess(A,B) where A and B are square matrices, and returns an ...
Returns: magnitude = 1 index = 3(从0开始,所以2Hz是3) 数字滤波器 数字滤波器用于一些不需要的频率信号。比如工频噪声(50Hz)正弦信号等。通常有两类滤波器: FIR(有限冲击响应滤波器) IIR(无限冲击响应滤波器) 虽然名字听起来很高大上,其实他们计算并不算复杂。本文侧重matlab应用,并不会涉及深奥的理论知识。
By splitting out theX,YandZcoordinates, a significant portion of the power calculation can be separated into a function containing only scalar operations. function signalPower = powerKernel(mapIndex, mastIndex) % Implement norm and dot product calculations via loop ...
