How to apply a threshold value to the cell array

Hi Friends,

I have a cell array matrix with C= 1*22. I want to apply a thresold to the cell array, all values less than (0.2) must be set to zero (0). The output dimention must be the same dimention of input cell array (1*22).

1- i have converted the cell to double

2- Applied the threshold

3- convert back the double to cell

I have applied this code, but could not got a cell with (1*22).

X=str2double(C); % converted the cell to double
 X(X <0.2)=0;  % Applied the threshold
C = num2cell(X); % convert back the double to cell

Works fine for me:

C=cellstr( rand(1,22)+"" );%Fake

X=str2double(C); % converted the cell to double
 X(X <0.2)=0;  % Applied the threshold
C = num2cell(X); % convert back the double to cell 

whos C

  Name      Size            Bytes  Class    Attributes

  C         1x22             2464  cell

Hi Matt,

The issue here in my matrix that i have inside the cell 22 matrices (each matrix inside every colomn in the cell is 30*30*20) as shown in the attached picture.

I think writing a for-loop would be most straightforward way to go. Something like this:

for k = 1:numel(C)
    C_k = C{k};
    C_k(C_k < 0.2) = 0;
    C{k} = C_k;
end

Dear Mr. Steve Eddins,

Thank you very much, It is really helping.
