insert new rows and movin data into new rows

clear all; clc;

n = 1000;

lambda = 480;

WAK = poissrnd(lambda,1,n);

WK(1) = WAK(1);

for i=1:n-1

WK(i+1) = WK(i) + WAK(i+1);

end

how to make WK multi-dimensional with : 1440*(t-1) <= WK(i) < 1440*t , suppose :

• for t=1 , WK(i) on row 1
• for t=2 , WK(i) on row 2
• for t=3, WK(i) on row 3
• dst.

Hint:

Use repmat() to copy the 1-D WK into additional rows or columns.

but I'm not sure what it's asking because I don't know if t is rows or columns, and every row or column has the same value, which is just WK(i).

Example 1-D WK = [ 1 2 3 4 5 6 7 8 9 10] I want to make WK being T-D WK like a : WK = [ 1; 2 3 4 5 6 7; 8 9 10] With (t-1)*2 <= WK < t*2

WK = [ 1 2 3 4 5 6 7 8 9 10]

WK = 1×10

1 2 3 4 5 6 7 8 9 10

WK = [ 1; 2 3 4 5 6 7; 8 9 10]

Dimensions of arrays being concatenated are not consistent.

As you can see, your desired output is not a valid matrix.

Please tell me what "t" is and give the 2-D matrix output you expect for that 1-D WK vector.

Do you mean just

WK2 = reshape(WK, [], 1440);

[Takim Mustakim]

i'm sorry

i mean is WK becomes

WK = [1 0 0 0 0 0 0 0 0 0 0; 2 3 4 5 6 7 0 0 0 0; 8 9 10 0 0 0 0 0 0 0]

[Image Analyst]

Well you could just do

WK = [1 0 0 0 0 0 0 0 0 0; 2 3 4 5 6 7 0 0 0 0; 8 9 10 0 0 0 0 0 0 0]

WK = 3×10

1 0 0 0 0 0 0 0 0 0 2 3 4 5 6 7 0 0 0 0 8 9 10 0 0 0 0 0 0 0

(obviously your "correction" didn't work, so I corrected your correction) or you could do

WK1 = [ 1 2 3 4 5 6 7 8 9 10]

WK1 = 1×10

1 2 3 4 5 6 7 8 9 10

WK = zeros(3, 10);
WK(1,1) = WK1(1,1);
WK(2, 1:6) = WK1(2:7);
WK(3, 1:3) = WK1(8:10) 

WK = 3×10

1 0 0 0 0 0 0 0 0 0 2 3 4 5 6 7 0 0 0 0 8 9 10 0 0 0 0 0 0 0

What's the use case? Why do you need to do this quirky thing anyway?

[Takim Mustakim]

not like what a mean but thank you for your response

[Image Analyst]

It's literally the output matrix you said WK should become, element by element.

And you never answered my questions: "What's the use case? Why do you need to do this quirky thing anyway?"

That might help me figure out what is wanted.

Looking at the second half of your original question, the best I can figure out what you mean is to use

WK2 = reshape(WK, [], 1440);
