Dear all, I have cell a= {[130 12] [130 9 67 66 2] [34 45 21] [55 6 77 8 12 343 ]} , how to remove the first and second element from the cell,. expect answer b = {[] [67 66 2] [ 21] [ 77 8 12 343 ]} Thanks in advance...
A cell array in which the first element is a function handle. Subsequent elements in the cell array are the arguments to pass to the callback function. A character vector containing a valid MATLAB expression (not recommended). MATLAB evaluates this expression in the base workspace. Use this ca...

First I’ll focus on pulling the basic algebra out of the loop. Scalar operators like .* and sqrt work on larger arrays in an element-by-element manner. Reductions, likesumandmean, can work along a chosen dimension of an N-dimensional input. Using these features and reshaping the data al...
