Interpolate positions between 2 matrix

Hello,

If you see the picture below, I am representing dinamically the blue point with a matrix and imagesc function. What I would like to do is filling the gap bewteen points with more points, so the final graph woould look like a line.

An example how I am plotting the graph

% First point position in the matrix
0 0 0 1 0 0 0 
0 0 0 0 0 0 0
0 0 0 0 0 0 0
0 0 0 0 0 0 0

% Next time period the matrix will have other values for the second "blue" point
0 0 0 0 0 0 0 
0 0 0 0 0 0 0
0 0 0 0 0 0 0
0 0 0 0 0 1 0

% I would like to get automatically a matrix that interpolate between both "1" values and get something like below to draw a line, 
0 0 0 1 0 0 0 
0 0 0 0 1 0 0
0 0 0 0 1 0 0
0 0 0 0 0 1 0

I hope to make myself clear,

Thanks in advance!

How about the following?

% First point position in the matrix
M1 = [0 0 0 1 0 0 0; 
0 0 0 0 0 0 0;
0 0 0 0 0 0 0;
0 0 0 0 0 0 0];

% Next time period the matrix will have other values for the second "blue" point
M2 = [0 0 0 0 0 0 0; 
0 0 0 0 0 0 0;
0 0 0 0 0 0 0;
0 0 0 0 0 1 0];

[row,col] = find(M1 | M2);

row2 = (1:4)';
col2 = round(interp1(row,col,row2));

M3 = zeros(size(M1));
M3(sub2ind(size(M3),row2,col2)) = 1;

The result is:

>> M3

M3 =

0 0 0 1 0 0 0

0 0 0 0 1 0 0

0 0 0 0 1 0 0

0 0 0 0 0 1 0

Brilliant, I think the idea will work wit my project!

Thank you so much
