1-3 微分. n 若要進行微分運算，可用diff 指令，例如：. syms a x f = sin(a*x^2); df = diff(f). 此時MATLAB 會自動決定f 的獨立變數是x，並對x 進行微分，得到的結果是. ,diff. Differences and approximate derivatives. Syntax. Y = diff(X) Y = diff(X,n) Y = diff(X,n,dim). Description. Y = diff(X) calculates differences between adjacent ... ,If X is a nonempty, nonvector p-by-m matrix, then Y = diff(X) returns a matrix of size (p-1)-by-m, whose elements are the differences between the rows of X . ,If X is a nonempty, nonvector p-by-m matrix, then Y = diff(X) returns a matrix of size (p-1)-by-m, whose elements are the differences between the rows of X . ,Higher-Order Derivatives of Multivariate Expression with Respect to Default Variable. Compute the second derivative of the expression x*y . If you do not specify ... ,Because you did not specify the differentiation variable, diff uses the default variable defined by symvar . For this expression, the default variable is x :. ,To illustrate how to take derivatives using Symbolic Math Toolbox™ software, first create a symbolic expression: syms x f = sin(5*x);. The command. diff(f). , 12.2 差分函數diff. 對於一個向量，差分函數在於求取該數列元素間之差異及其導數，相關指令格式如下： Y = diff(X) Y = diff(X,n) Y = diff(X,n,dim),此MATLAB 函数计算沿大小不等于1 的第一个数组维度的X 相邻元素之间的差分： ... 如果 X 是不为空的非向量p×m 矩阵，则 Y = diff(X) 返回大小为(p-1)×m 的矩阵，其 ... ,MATLAB. 符號運算功能. • Symbolic Math Toolbox ... 微分運算- diff. ▫ diff(f,x,n) ... diff(f) ans = 9*x^2+4*x+1. ▫ 二次微分diff(f,2). >> syms a x. >> f = sin(a*x^2).
