Hello everyone,
I have a question regarding how to modify a text array in Matlab which contains numbers between two "_" symbols. Here some examples:
- If the string has the following structure: "Gas_1_O2" I expect the following result: "Gas_O2". This should work for every number between two "_" symbols.
- If the string has another structure nothing should happen (e.g. "Time" or "Flow_Fluidization").
The text string will later on be used for renaming a table.
I tried with the function extractBetween but it did not worked as I expected.
Thanks for your support.
Best,
Joseba

a="Gas_1_O2";
regexprep(a,'\_\d*.?\d*\_','_')

"The code was put keeping only numbers (including decimals)..."
Remember that . by itself matches all characters, not just the decimal point / period chraacter.

True Stephen that‘s why I used [\.] to preserve dot character in the latter comment.

You can use regular expressions for this task:
str1='Gas_1_O2';
str2='Flow_Fluidization';
regexprep(str1,'_[0-9]*_','_')
regexprep(str2,'_[0-9]*_','_')
