concatenate everything in a cell array matlab

CONCATENATE EVERYTHING IN A CELL ARRAY MATLAB CODE

horzcat is equivalent to using square brackets to horizontally concatenate or append arrays. Separate elements with semicolons for vertical concatenation or commas for horizontal concatenation. C horzcat (A1,A2,An) concatenates A1, A2,, An horizontally. Use the standard square bracket concatenation operator. finally concatenate them, you may use horzcat for horizontal concatenation. append the empty cell to all the smaller cell arrays. Find the length of the longest cell array. I am trying to concatenate all of the words to make a single array. I'm assuming you want to retain the data of one cell array as a column.

If you really want to use Aggregate use variant using StringBuilder proposed in comment by CodeMonkeyKing which would be about the same code as regular String.Join including good performance for large number of objects: var res = words.Aggregate( C horzcat (A,B) concatenates B horizontally to the end of A when A and B have compatible sizes (the lengths of the dimensions match except in the second dimension). I have a cell array containing 750 'documents' (750 arrays of words within the single cell array). More information - MSDN: Aggregate Queries Remember that aggregate queries are executed immediately. Using the dot-notation, one simply calls a method on an IEnumerable object.

Both VB and C# support aggregates as extension methods. Both VB and C# have support for aggregates. You can generate a comma-separated list from either a cell array or a MATLAB structure. Examples from T-SQL include min, max, and sum. When used with large and more complex data structures like MATLAB structures and cell arrays, comma-separated lists can help simplify your code. (current, next) => current + ', ' + next) Īn aggregate is a function that takes a collection of values and returns a scalar value. '', // start with empty string to handle empty list case. Use aggregate queries like this: string words = a cell array) and indexing is much simpler, neater, much more efficient, less buggy, and easier to debug. For regular code use String.Join as shown in the other answer Because this does not use a StringBuilder it will have horrible performance for very long sequences. Refer to sets of cells by enclosing indices in smooth parentheses, (). Cell arrays commonly contain either lists of text, combinations of text and numbers, or numeric arrays of different sizes. Lets say cellarray1 is an M x N cell array and cellarray2 is M x P. This answer shows usage of LINQ ( Aggregate) as requested in the question and is not intended for everyday use. A cell array is a data type with indexed data containers called cells, where each cell can contain any type of data. You can combine cell arrays using array concatenation operator.
