Is there any way that I can check to see if any of the stings in my cell array are inside of the sentence? your location, we recommend that you select: . Hi, I am am trying to determine the number of rows in a matrix using matlab, I usually use. More Answers (1) GeeTwo on 7 Dec 2022 at 11:58 If I'm understanding correctly, cellfun (@numel,strfind (string (val),"EXPERIMENT")) Paul Hinze on 7 Dec 2022 at 12:08 end. if i enter; cellfun(@numel,strfind(string(stimuli),"EXPERIMENT")), where stimuli is my variable i get following error message: Error using string. Alternative: Theme Copy index = cellfun (@ (x) x==5, C, 'UniformOutput', 1); Or the long and I have an cell array 'inputs' with strings and numbers and I need find where one of the strings from an another cell array of strings is located. I wanted to do this recently and was surprised none of the built-in string-based functions worked for this so I delved into regexp for the first time will give you the indices into your string to the start of any matching elements. To find my string as pattern matching/part of the string, we can use the contains a () function which can then, be passed to the find() function to get the indices. I would suggest using strmatch instead of strfind. I had to find all the instances of specific string in a large cell array, and used Chad's answer to get started. As it can be seen that all elements of the above array contain all strings so, we shall move ahead. I want to find the indexes of A which contains a specific string from B and i want to repeat that for every element of B. I used the following function to find out the indexes for one element of B at a time. Nice solution. Select the Extract: option from the Ablebits Data tab > Text group.
