如何在MATLAB中获得多行控制台输出？使用horzcat给我一个错误
 

fprintf(['# True Positive: %d \n',... '# False Positive: %d \n',... '# True Negative: %d \n',... '# False Negative: %d \n,',... numTruePos,... numFalsePos,... numTrueNeg,... numFalseNeg]); 但是我得到了错误：

??? Error using ==> horzcat The following error occurred converting from logical to char: Error using ==> char Conversion to char from logical is not possible. Error in ==> toyProblem at 40 fprintf(['# True Positive: %d \n',...

您似乎在错误的位置使用了格式字符串的右括号[ ] 。尝试这个：

fprintf(['# True Positive: %d \n',... '# False Positive: %d \n',... '# True Negative: %d \n',... '# False Negative: %d \n'],... %# Moved it to here... numTruePos,... numFalsePos,... numTrueNeg,... numFalseNeg); %# ... from here
