Error message: "undefined function for input arguments of type 'logical' "

What does the error message "undefined function for input arguments of type 'logical' " indicate?

Answer 1

[Matt Fig]

It indicates that there is no function by the name that you called for inputs of the logical type. So either you called a function that does exist, but you called it with an input that it didn't expect, or there just is no such function.

[Syeera Riza]

how to solve when the error message : Undefined function 'boxcount' for input arguments of type 'logical'. and how to recognize 'boxcount'?

[Stephen23]

boxcount is not an inbuilt MATLAB function. You need to download this FEX submission

https://www.mathworks.com/matlabcentral/fileexchange/13063-boxcount

and then unzip into onto the MATLAB search path (or into the current directory).
