Error using ^ Inputs must be a scalar and a square matrix. To compute elementwise POWER, use POWER (.^) instead. 此时可以利用arrayfun函数解决该问题 f = @(x)x^2; arrayfun(f,[2 3]) 结果为: ans = 4 9 所以,为了避免argin只能为scalar,最好在定义的时候就向量化 f = @(x)x.^2; f(...

On the first line, you are defining num and setting its value to 10. On line 2, writing if num == 10: tests the value of num compared to 10. Notice the colon at the end of the line. Next, line 3 must be indented in Python’s syntax. On that line, you are using print() to...
Bounds must be nonnegative. To fix the size of the first dimension of inputUto 3 and set the second dimension as variable size with upper bound of 2, call: assert(all(size(U)>=[3 0])); assert(all(size(U)<=[3 2])); Specify Size of Individual Dimensions ...
Can be an array of two window pointers. In this case, the first window pointer is taken to refer to the participant screen, and the second to an operator screen. In this case, a minimal interface is presented on the participant screen, while full information is shown on the operator ...
Functions are also m-files. The first line in a function file must be of this form: function [outarg_1, ..., outarg_m] = myfunction(inarg_1, ..., inarg_n) The function name should be the same as that of the file (i.e. function "myfunction" should be saved in file "my...
The first argument, F, is a function handle or an anonymous functionthat defines F(x). Arguments beyond the first four, Q = QUADTX(F,a,b,tol,p1,p2,...),are passed on to the integrand, F(x,p1,p2,..). QUAD Numerically evaluate integral, adaptive Simpson quadrature. Q = QUAD(FUN...
% FID is a scalar MATLAB integer valued double, called a fileidentifier. You use % FID as the first argument to other file input/output routines, such as FREAD and % FCLOSE. If FOPEN cannot open the file, it returns -1. % % FID = FOPEN(FILENAME,PERMISSION) opens the file FILENAME...
