I am trying to index from Cell array

3 次查看(过去 30 天)
I have a nested cell array
pos{1X4}
>> {6830X1}{6824X1}{6834X1}{6826X1}{6842X1}{6840X1}{6836X1}{6844X1}{6837X1}{6833X1}
I am trying to index from cell array, but I am getting Unable to use a value of type cell as an index.
position_0{tr} = pos(time_0);

Both the array are 11, I am still figuring why I am getting this errorr-Index exceeds the number of array elements. Index must not exceed 11.
I am attcahing the Raw here now.

I've just downloaded the raw data
The 1st cell of both time_0.mat and pos.mat is empty so that would cause a problem.
pos =
1×11 cell array
{0×0 double} {6830×1 double} {6824×1 double} {6834×1 double} {6826×1 double} {6842×1 double} {6840×1 double} {6836×1 double} {6844×1 double} {6837×1 double} {6833×1 double}
time_0 =
1×11 cell array
{0×0 double} {[1002]} {[1002]} {[1002]} {[1002]} {[1002]} {[1002]} {[1002]} {[1002]} {[1002]} {[1002]}
Try the following:
position_0 = cellfun(@(p,t) p(t), pos, time_0, 'UniformOutput', false);
Bear in mind that the 1st index of position_0 will also be empty
position_0 =
1×11 cell array
{0×0 double} {[86.9711]} {[86.9943]} {[87.0181]} {[87.0761]} {[87.0062]} {[87.0405]} {[86.9515]} {[86.9467]} {[87.0836]} {[86.9525]}

It sounds like time_0 is a cell.
time_0 should to be positive integers or logical values
I'm assuming that time_0 is a cell containing an array of indices.
If that is the case, you can try something like:
position_0{tr} = pos([time_0{:}]);
