Minimum for different sized cell arrays

How do i find minimum value from indexing, it is simple for a matrix but how to do the same for different cells?

x & y are same sized

For matrix

x=10*rand(10,1300);
y=100*rand(10,1300);

      idx=find(abs(x-1<0.005));
      miny=min(y(idx))

For different sized cell arrays,

x&y= 10x1300 cell array containing the same different sized cells. Both are

Columns 1297 through 1300
    [1×23 double]    [1×29 double]    [1×23 double]    [1×25 double]
    [1×25 double]    [1×25 double]    [1×25 double]    [1×27 double]
    [1×25 double]    [1×27 double]    [1×27 double]    [1×25 double]
    [1×29 double]    [1×29 double]    [1×25 double]    [1×23 double]
    [1×25 double]    [1×23 double]    [1×27 double]    [1×27 double]
    [1×27 double]    [1×23 double]    [1×21 double]    [1×23 double]
    [1×29 double]    [1×27 double]    [1×27 double]    [1×27 double]
    [1×21 double]    [1×21 double]    [1×29 double]    [1×27 double]
    [1×25 double]    [1×25 double]    [1×21 double]    [1×27 double]
    [1×25 double]    [1×25 double]    [1×25 double]    [1×23 double]   

index=cellfun( @(X) find(abs(X-1)<0.005), x, 'uniform', 0);

index results Columns 1297 through 1300, Index returns some zero cells.

How do i do the same to find the min as for a matrix, miny=min(y(idx)), a single value result.

[Joseph Lee]

Having error.

miny = min (cellfun( @(Y) Y(index),y,'uniform', 0)) ;

Function 'subsindex' is not defined for values of class 'cell'.

Answer 1

[Walter Roberson]

To get the overall minima over a cell array without caring what the position is,

min( [YourArrayName{:}] )

[Joseph Lee]

It requires the index first to get a set of Y values then get the overall minima from it without caring what the position is.

For a matrix it would be y(index) < gives a set of values

[Walter Roberson]

min( cell2mat( cellfun(@(Y, IDX) Y(IDX), y, index, 'uniform', 0) ) )

[Joseph Lee]

thanks, ( cellfun(@(Y, IDX) Y(IDX), y, index, 'uniform', 0) ) worked

but there is an error with cell2mat, might be due to the zeros

Error using cat Dimensions of matrices being concatenated are not consistent.

Error in cell2mat (line 78)
        m = cat(1,m{:});

Result from ( cellfun(@(Y, IDX) Y(IDX), y, index, 'uniform', 0)
