MATLAB: Search for a word in a string with complete match

Question

Hi all,

I have a string and a cell as follows

StringText = 'High rotation speed changes the parameter RevolutionChange'
WordCell = {'Slip' , 'GearRatio','Revolution','RevolutionChange'}

When I use regular explression to find the line parameters in StringText, the 3rd and 4th indices are obtained as outputs. I need only the 4th index to be the output

Index = regexp(StringText, WordCell, 'match')

Present output = 1×4 cell array => {0×0 cell} {0×0 cell} {Revolution} {RevolutionChange}

required output = 1×4 cell array => {0×0 cell} {0×0 cell} {0x0 cell} {RevolutionChange}

Thanks

Answer 1

How about the following way?

StringText = 'High rotation speed changes the parameter RevolutionChange';
WordCell = {'Slip' , 'GearRatio','Revolution','RevolutionChange'};
% Split text into words
WordsInText = split(StringText);
% Find word(s) in WordCell used in the StringText
idx = ismember(WordCell,WordsInText);
% Show word(s) used in the StringText
WordCell(idx)

ans =

{'RevolutionChange'}
