用vpa函数没问题，但结果应该仍然是x。程序改成如下就可以了：syms x y；vpa(x)
I have the following simplified function: functionout = fnName() s = [ ]; s.x = 10;% This is the line where I get the error. end It runs fine in MATLAB but when I use MATLAB Coder to generate code for it, I get the following error: ...

This MATLAB function approximates the integral of the function z = fun(x,y) over the planar region xmin ≤ x ≤ xmax and ymin(x) ≤ y ≤ ymax(x).

MATLAB Online에서 열기 You have assigned numeric variables to‘x’, and to‘D’, so‘f’is not a function of anyvariable. Perhaps you want: atbt = [0.36 0.5]; lims = [0 0.5238 1.04718 1.5708 2.0944 2.6180 pi]; x = linspace(0, pi, 15)...
By default, numbers in MATLAB are of the data typedouble. You can use theclassfunction to verify a variable's type. x = 100; xtype = class(x) xtype = 'double' Use thedoublefunction to convert variables that are not double precision to typedouble. ...
Function ‘*’ is not defined for values of class ‘uint8’ 1个字节无符号整型最大只能存储数据为255,对图片的操作所以很容易溢出。 2. matlab图像类型转换 matlab读入图像的数据是uint8,而matlab中数值一般采用double型(64位)存储和运算。所以要先将图像转为double格式的才能运算,区别如下: ...
X= str2double(str)converts the text in stringstrto a double-precision value. In a chart that uses MATLAB®as the action language,str2doublereturns a complex value. In a chart that uses C as the action language,str2doublereturns a real value. ...
最近也在接受一下非电子类的培训，也是艰难的不行，感觉是真的去搬砖了一样，不过还是蛮有意思的，
