Converting string array to float array

I have a string array of the format

"[1,1]"

"[2,1]"

"[3,1]"

How can you convert into double array?

Answer 1

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
