Cannot concatenate strtok's output variable. strcat and strtok

I’ve spent hours on this program and have put several hours online searching for alternatives to my methods and have been plagued with crashes and errors all evening… I have a few things I'd like to achieve with this code. First I’ll explain my problems, then I’ll post the code and finally I’ll explain my need for the program. The program outputs just the single words and the concatenate function does nothing. This seems like it should be simple enough to fix... My first problem is that I cannot seem to get the concatenate function to work, I used the generic strcat function which didn't work

问题 a1=ac_tree_birch_NewYork_ext a2=bc_animal_dog_Washington_des How do I separate the text in the cells by the "_", since there is varying length of the cell values. I would like to use a formula, and not text to columns. Thanks 回答1: Use the SUBSTITUTE function to change all underscores (e.g. CHAR(95) ) to a large number of spaces (typically the entire length of the original string) and peel out the padded pieces with the MID function. Finish off with TRIM and an IFERROR 'wrapper'. In B1 as,

问题 I want to read a PLY file to a MATLAB matrix starting from the next line of the string end_header using the dlmread function as suggested in this SOF question. Sample PLY file is given here. Currently the starting line is hardcoded as follows, but it is not suitable as the number of header rows in a PLY file may change. data = dlmread(fileName, ' ', 14, 0); 回答1: There are a multitude off different ways you could do this. One option is to use textscan to read in the entire file and a mix of
