As an alternative, you can convert a cell array of character vectors to a string array using thestringfunction. MATLAB displays strings in string arrays with double quotes, and displays characters vectors in cell arrays with single quotes. Get C = {'Mercury','Venus','Earth'} C =1x3 cell{...
stringCtor(char[]?value){if(value==null||value.Length==0)returnEmpty;stringresult=FastAllocateString(value.Length);Buffer.Memmove(elementCount:(uint)result.Length,// derefing Length now allows JIT to prove 'result' not null belowdestination:refresult._firstChar,source:refMemoryMarshal.GetArrayData...
source:refMemoryMarshal.GetArrayDataReference(value));returnresult; } 这里的两个重要步骤是: 根据数组长度使用FastAllocateString分配内存。FastAllocateString是在 .NET Runtime 中实现的,它几乎是所有字符串分配内存的基础。 调用Buffer.Memmove,它将原来数组中的所有字节复制到新分配的字符串中。
Create a 3-by-3 array using adurationas the fill value but specify "string"asclassname. MATLAB converts the duration to a string. f = duration(0,30,0,Format="hh:mm"); C = createArray(3,"string",FillValue=f) C =3x3 string"00:30" "00:30" "00:30" "00:30" "00:30" "00:...
https://stackoverflow.com/questions/44303189/c-macro-to-create-a-string-arraySo what do you think is easier for someone else to understand -- simply declaring/initializing a char* array in your code or using preprocessor "macro magic" programming that takes as input virtually the same...
