Converting Cell matrix to a Numeric Matrix

I have a cell matrix as shoown below.

B={'2' '3' '5'; '4' '7' '2'; '7' '5' '2'}
B =

  3×3 cell array

    {'2'}    {'3'}    {'5'}
    {'4'}    {'7'}    {'2'}
    {'7'}    {'5'}    {'2'}

I want to convert it a numeric matrix like as follows:

    
A =

     2     3     5
     4     7     2
     7     5     2

B={'2' '3' '5'; '4' '7' '2'; '7' '5' '2'}

B = 3×3 cell array
    {'2'}    {'3'}    {'5'}
    {'4'}    {'7'}    {'2'}
    {'7'}    {'5'}    {'2'}

C = cellfun(@(x)str2double(x),B)

C = 3×3

2 3 5 4 7 2 7 5 2

Thanks Stephan. It works.

Or, by simply reading the str2double documentation, you can easily have much much more efficient code:

B = {'2','3','5';'4','7','2';'7','5','2'};
M = str2double(B)

M = 3×3

2 3 5 4 7 2 7 5 2

Woow. That's one is more easier to remember. Thanks to you once again Stephen.
