I saved a matrix in a file.txt; the type of matrix is as follow:
file: 0.010993,0.21973,0.012142,0.49897,0.24634,0.01183
When I open the matrix by using
Matrix= dlmread( 'File.txt') ) ;
The matlab take only 4 number after the point, where Matrix:
Matrix: 0.0110 0.2197 0.0121 0.4990 0.2463 0.0118
I don't want to change the numbers after the matrix.

I suspect the full values are there. However, by default MATLAB only displays 4 decimal places. If you look at the original and displayed values, you can see they've been rounded to 4 decimal places. However, the full value is still there. This is just a display thing.
You can modify the command window output display using the format function. See the available options here.
