reshape with a huge matrix
显示 更早的评论
my matrix is constructed like this: A=[118*9| 118*9| 118*9|118*9|......]
i have a problem using reshape and mean function:
i want to make the mean for each block (118*9) using mean(matrix,2) tp get mean_A=118*9 n times.
i thought i should reashape my matrix in this form:
% reshaped=
[118*9
118*9
118*9
.
.
.
]
and then use the mean. i did Not get it. could you help:
i want to get matrix like this

Clearly Rica liked your answer, but I have no idea what you are doing. What are some sample data and index?

I am not sure what you mean by your notation. Is this what you are looking for?
n = 10;
x = repmat(1:(118*9), 1, n);
y = reshape(x, 118*9, n);
