If the data only contains 0's and 1's ..
data = [
"01"
"01"
"10"
"10"
"01"]
data = 5×1 string array
"01" "01" "10" "10" "01"
data = double([extractBefore(data,2) extractAfter(data,1)])
data = 5×2
0 1 0 1 1 0 1 0 0 1

data = ["01";"01";"10";"10";"01"]
data = 5×1 string array
"01" "01" "10" "10" "01"
M = char(data)-'0'
M = 5×2
0 1 0 1 1 0 1 0 0 1

Try something like this —
sv = ["01"
"01"
"10"
"10"
"01"];
cv = char(sv);
for k = 1:size(cv,1)
data(k,1) = str2double(cv(k,1));
data(k,2) = str2double(cv(k,2));
end
data
data = 5×2
0 1 0 1 1 0 1 0 0 1
.
