Ran in:
S = ["[1,1]";"[2,1]";"[3,1]"]
S = 3×1 string array
"[1,1]" "[2,1]" "[3,1]"
Method 1:
M = sscanf(join(S,''),'[%f,%f]',[2,Inf]).'
M = 3×2
1 1 2 1 3 1
Method 2:
M = cell2mat(arrayfun(@str2num,S,'uni',0))
M = 3×2
1 1 2 1 3 1
Method 3:
M = reshape(str2double(regexp(join(S),'\d+','match')),2,[]).'
M = 3×2
1 1 2 1 3 1
