The end command also serves as the last index in an indexing expression. In that context, end = (size (x,k)) when used as part of the k th index. Examples of this use are X (3:end) and X (1,1:2:end-1). When using end to grow an array, as in X (end+1)=5, make sure X exists first. Examples This example shows end used with for and if.

Since R2023a. Create two tables and perform a logical OR of them. The row names (if present in both) and variable names must be the same, but do not need to be in the same orders. Rows and variables of the output are in the same orders as the first input. A = table ( [0;2], [0;4],VariableNames= [ "V1", "V2" ],RowNames= [ "R1", "R2" ]) A= 2×2 ... Each loop requires the end keyword. It is a good idea to indent the loops for readability, especially when they are nested (that is, when one loop contains another loop): A = zeros (5,100); for m = 1:5 for n = 1:100 A (m, n) = 1/ (m + n - 1); end end. You can programmatically exit a loop using a break statement, or skip to the next iteration of ... The reshape function changes the size and shape of an array. For example, reshape a 3-by-4 matrix to a 2-by-6 matrix. A = [1 4 7 10; 2 5 8 11; 3 6 9 12] A = 3×4 1 4 7 10 2 5 8 11 3 6 9 12. B = reshape (A,2,6) B = 2×6 1 3 5 7 9 11 2 4 6 8 10 12. As long as the number of elements in each shape are the same, you can reshape them into an array ...The special end operator is an easy shorthand way to refer to the last element of v: v(end) % Extract the last element ans = 14 The end operator can be used in a range: v(5:end) % Extract the fifth through the last elements ans = 2 11 7 14 You can even do arithmetic using end:Function argument validation is declarative, which enables MATLAB ® desktop tools to extract information about a function by inspection of specific code blocks.
