function T=danyuanzhu_3_7(miu) N=100; L=100; b=double(1.12); %miu=double(1.0925); for Q=1:1:101 ka=10*(Q-1)/100; …… …… 运行之后结果是:未定义与 'double' 类型的输入参数相对应的函数 'danyuanzhu_3_7',请问要怎么解决?
用double函数将符号型变量变为数值型变量，要求符号变量的值是可以转换的，而你举的例子中x并未赋值，怎么可能转换？用vpa函数没问题，但结果应该仍然是x。
如果你标记一个变量，你会在MatLab编辑器的底部看到下面的一行：“3 Usage of”x“Found”如果你已经定...
For the automated workflow, do not use explicit double or single casts in your MATLAB® algorithm to insulate functions that do not support fixed-point data types. The automated conversion tool does not support these casts. Instead of using casts, supply a replacement function. For more informa...

[Calling the integral function and passing the desired limits as 0 <= x <= 1; 0 <= y <= 2)] [Mathematically, the double integral of 1./(sqrt(x.^3 + y.^2)) is 2.9012] Output: Conclusion Integral2 function can be used in MATLAB to get the double integral of a function. Doub...
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: ...
把后两句这样改：Gx = conv2(basis(1,:),basis(2,:)');Gy = conv2((basis(2,:)),(basis(1,:))');
In this MATLAB code, we first declare a function namedfun. After that, we approximate thedouble integralof the given function over the specified region R using theintegral2()function. fun =@(x,y)((x + y).^2-(1+ x - y).^3); ...
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. ...
