How to keep only numbers in a cell (.xlsx file)?

10 次查看(过去 30 天)
I have an .xlsx file. In one column there are numbers and text in each cell (e.g. 0.562550 (AHV)).
How could I keep ONLY the number of each cell (e.g. ONLY the 0.562550) ??
I am uploading the file in order to understand.
Thank you in advance

c = readcell('test.xlsx');
data = cellfun(@(C) str2double(regexprep(C, '\(.*', '')), c)

Good point. Though I might suggest adding a size to the sscanf() to prevent it from trying to look for more values, and as a guard against the possibility of having a second value that looked like a number in the cell.

True, this works only for simple situations like this. Otherwise, regexp would guard against those sloppiness with sscanf and more complex formats. Now I've modified it, tanx!
