Y= log(X)returns the natural logarithmln(x)of each element in arrayX. Thelogfunction’s domain includes negative and complex numbers, which can lead to unexpected results if used unintentionally. For negative and complex numbersz = u + i*w, the complex logarithmlog(z)returns ...

Exponent values, returned as a scalar, vector, matrix, multidimensional array, table, or timetable of the same size asX. The values inFandEsatisfyX = F.*2.^E. Tips This function corresponds to theANSI®Cfunctionfrexp()and the IEEE®floating-point standard functionlogb(). Any zeros inX...
主动旋转和被动旋转:主动旋转是指将向量或坐标系逆时针围绕旋转轴旋转,被动旋转是对坐标轴进行的逆时针旋转,相当于主动旋转的逆操作。 0x01 rotate函数 rotate是matlab官方提供的三维旋转图形函数。 rotate通过给定轴角,使用下列公式转换得到旋转矩阵R,再通过R得到旋转后的图像: ...

This MATLAB function plots x- and y-coordinates using a base-10 logarithmic scale on the x-axis and the y-axis.
Y= log1p(X)computes the natural logarithmlog(1+X)for each element in arrayXwithout explicitly computing1+X. IfX < -1, thenYis complex. This function is more accurate for small real values inXbecause it compensates for the round-off error in1+X. ...
In this chapter, the semilog scale plot (for x-axis) in MATLAB is presented and described. In this regard, several examples and exercises for each section of the chapter are presented. The exercises that include writing the codes, executing them, and ach
This MATLAB function takes a matrix of net input vectors, N and returns the S-by-Q matrix, A, of the elements of N squashed into [0, 1].
