cell-array

问题 I created 1D array which shows words and in which sentences they occur. After that I took the intersection to show which word occurs with which each of other remaining words in sentence: OccursTogether = cell(length(Out1)); for ii=1:length(Out1) for jj=ii+1:length(Out1) OccursTogether{ii,jj} = intersect(Out1{ii},Out1{jj}); end end celldisp(OccursTogether) the output of above code is as below: OccursTogether{1,1} = 4 11 14 OccursTogether{1,2} = 1 OccursTogether{1,3} = [] OccursTogether{1,4} =

问题 I need to plot a cell array with the following format in Matlab: {[vector1], [vector2], ...} Into a 2D graph with the index of the vector as the y and the vector as the x ([vector1], 1), ([vector2], 2), ... 回答1: Here's a simple option: % some arbitrary data: CellData = {rand(10,1)*50,rand(10,1)*50,rand(10,1)*50}; % Define x and y: x = cell2mat(CellData); y = ones(size(x,1),1)*(1:size(x,2)); % plot: plot(x,y,'o') ylim([0 size(x,2)+1]) so you plot each vector of x on a separate y value: It will

问题 I have looked for the proper way to access a given field of a struct and the manual and online searches didn't help. Formally, let MyStruct be a 1xn struct variable. It's easy to list all the elements stored in a field with: MyStruct.Thisfield ans = 0.7010 ans = 0.310 ans = 0.444 etc. Now the only way I found to be able to access an element of this is to use a temporary variable, e.g. temp={MyStruct.Thisfield} and then temp{1,2} etc. I think it's clumsy but can't figure out what else to do.

问题 I have a large dataset split into 5 files (each has 15000 attributes, first file contains header (attribute names) and 9999 records, and the other 4 contain 10000 records). Using textscan, I have created 5 cell arrays which have to be merged and don't know whether this approach is appropriate or it would be better to directly read all 5 files into single cell array. Anyway I would be thankful if anyone of you could show the way to merge several cell arrays into single cell array or read

问题 I have a mat file which contains 2 different cells containing matrices of different size. I need to convert that data into a numpy array using h5py for an experiment (I'm new in h5py. I thought it was as easy as it is explained here Reading the file works well, putting the data in the numpy array also works well, but I need the value representation of each position inside each matrix inside each cell, taking into account that when I print for example np.array(x[0][1]) , I receive just the

A contains unique column vectors of M(1:3,:) , in addition to the corresponding values in M(4,:) A(1:3,:) = unique(M(1:3,:

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: Counting values by day/hour with timeseries in MATLAB This is an elementary question, but I cannot find it: I have a 3000x25 character array: 2000-01-01T00:01:01+00:00 2000-01-01T00:01:02+00:00 2000-01-01T00:01:03+00:00 2000-01-01T00:01:04+00:00 These are obviously times. I want to reformat the array to be a 3000x1 array. How can I redefine each row to be one entry in an array? (Again, this is simple, I'm sorry)

问题 I have a similar question to my previous one. This time the form of the nested structure looks like this: Sizes = [2, 5, 8, 6, 3]; cells = 5; for i = 1:cells for j = 1:Sizes(i) a(i).b.c(j).d = rand(1,1); end a(i).b.Size = Sizes(i); end Again I would like to put all the d values of a(:).b.c(:) into a single cell array that contains 1 x cells cells. Here is my solution using cellfun but I would like to avoid this function: ab = [a.b]; abc = {ab.c}; abcd = cellfun(@(x) [x.d], abc, 'UniformOutput

问题 >> C = [{1} {2} ; {'@CF'} {2}] C = [ 1] [2] '@CF' [2] >> whos C Name Size Bytes Class Attributes C 2x2 478 cell How can I convert C into double so that: >> C C = 1 2 NaN 2 I've tried str2double(C) . It returns: NaN NaN NaN NaN 回答1: Find the non numeric values with isnumeric, queried by cellfun. Use that with logical indexing to extract the numeric values: C = [{1} {2} ; {'@CF'} {2}]; isnum = cellfun(@isnumeric,C); result = NaN(size(C)); result(isnum) = [C{isnum}]; 回答2: C = [{1} {2} ; {'@CF'}
