从提示看,你程序中某个算式中含有sym字符,你却要用double命令转成数值,这是转换不了的,就会有这样的提示。请看清提示是哪一行代码有错,针对这行代码查找下问题,再改正。
-4.5031370E-03 -1.1870213E-01 These values are still not manipulatable. When I then try ThemeCopy double(A) I get the values from the 'baskets' they're in, ThemeCopy ans = 1 2 Thus, how do i get the categorical arrays as double values such that I can work with them?1...
"Error using double Conversion to double from py.numpy.ndarray is not possible." Any idea why it doesn't work or if there is an alternative way to convert ndarray in matlab array? Thansk in advance, Giacomo For reference the output of details(ans) is ...
sym是符号类型,要转为double需要使用以下代码:sym x x1=double(x)
只要result转换成MWNumericArray类,那么就好办了,利用C#的转换类型函数就能转换成C#中的其他类型了,如Convert.ToDouble()一下就变成Double类型了。 b.字符串(需要用到MWCharArray和MWArray转换) MWCharArray FileName =myString; MWNumericArray sensitivity;
出错 Untitled4 (line 3)表示第三行出错,后面的代码就不运行了,所以后面代码你不必贴上来。第二行代码T(1)=1; 指定了T是个双精度(double)类型数据,所以第三行运行时加入符号(sym)类型数据会出错,解决办法:将第二三行代码替换为T = [1; K];
% Convert Var_2 and Var_3 to double HoldNames={'var_2','var_3'}; % Below Code is working. But I think there might be more matlab-like way to do it. for i = 1:length(HoldNames) val(i) = find(strcmpi(T.Properties.VariableNames,HoldNames(i))); end for i = 1:length(Hold...
