I have a character matrix A that I want to convert to numbers B, but it doesn't work with str2num. Any tips? I tried B = str2num(A) but gives B = [].
A = ['02';'06';'07'];
B = [2;6;7];

Ran in:
Your example shows a character matrix, not a "vertical string vector" nor a "character vector".
This is a vertical string vector:
S = ["02";"006";"4"]
S = 3×1 string array
"02" "006" "4"
This is a character vector:
V = '0001'
V = '0001'
whos
Name Size Bytes Class Attributes S 3x1 258 string V 1x4 8 char
