Set empty vector equal to zero? MATLAB Answers - MATLAB
Appending a vector to an empty MATLAB matrix. Ask Question 15. 5. I've got MATLAB code inserting n-dimensional points (n >1) into a matrix (myPointMatrix) and am having thoughts about how to insert the first point. Right now the program checks the size of myPointMatrix before inserting a point. If it is 1x1, myPointMatrix is set equal to the current point. Otherwise the current point is... If none are found, find returns an empty, 0-by-1 matrix. In general, find(X) regards X as X(:) , which is the long column vector formed by concatenating the columns of X . indices = find(X, k) or indices = find(X, k, 'first') returns at most the first k indices corresponding to the nonzero entries of X .

Adding empty strings to a cell array matlab - Reddit

A vector is either an m?1 matrix (a column vector) or a 1?n matrix (a row vector). To create a vector with matrix , one may also pass the dimension of the vector and a table of vector components as argument to matrix :...
The way this is supposed to be done, and the simplest is. a=struct('x',cell(1,N)); If you fix the missing "tic" and add this method to the benchmarking code presented by jerad, the method I propose above is a bit slower than repmat but much simpler to implement, here is the output:

  • But an empty array does not preallocate the array. If you do not want to use zeros you could preallocate using a NaN array. If you do not want to use zeros you could preallocate using a NaN array. Jan
