MATLAB: Creating a matrix in matlab using a text file

inputmatrixoutputpythontextfile

type output.txt;
A = readmatrix('output.txt');
A
This is the output.txt file
[[1 2 2 0 0]
 [2 1 0 0 2]
 [2 0 1 2 0]
 [0 0 2 0 4]
 [0 2 0 4 0]]
A =
   NaN     2     2     0   NaN
   NaN     1     0     0   NaN
   NaN     0     1     2   NaN
   NaN     0     2     0   NaN
   NaN     2     0     4   NaN
but when i passed it as a input to A the first and last rows are displaying NaN.can someone rectify it.

It's the brackets, [], that confuses Matlab. Try
A  =  readmatrix( 'output.txt', 'Whitespace',' []' );
I have R2018b so I can't test it.
Your output.txt looks more like the right hand side of an assignment in an m-function. Try
A = [[1 2 2 0 0]
     [2 1 0 0 2]
     [2 0 1 2 0]
     [0 0 2 0 4]
     [0 2 0 4 0]]
in the command window (copy and paste).
