how to fit an array in matrix?
显示 更早的评论
Hi All,
is there any function or command to fit (insert) an array in a 2D matrix by shifting the later arrays one step down so not to overwrite that array

If the number of columns are the same, you can insert array2 into array 1 starting at row k like this:
outputArray = [array1(1:k-1,:); array2; array1(k:end,:)];
If the number of rows are the same, you can insert array2 into array 1 starting at column k like this:
outputArray = [array1(:, 1:k-1), array2, array1(:, k:end)];
If the number of rows and columns are different, then you'd basically have to paste the smaller on onto the larger one, overwriting values, or else insert a slab of zeros and then overwrite the zeros.

What are the sizes involved? E.g., are you trying to insert a row at the front? E.g., is this what you want (assumes same number of columns for new_row and my_matrix):
new_row = whatever
my_matrix = whatever
my_matrix = [new_row;my_matrix]; % <-- insert new row at front
