Import data doesn't import some of the values

1 view (last 30 days)
When I try to import a matrix into MatLab from a text file, it doesn't import some of the values. An example of values that is not imported is 2.134282. An example of values is imported is 0.00277.

The file that I have attached contains the matrix that I can't import.

Have you tried readmatrix()? It seems to import the value correctly
format long
M = readmatrix('weighted_network.txt');
x = M(26, 35)
Result
>> x
x =
2.134282000000000

T = readtable('weighted_network.txt') % you can also use readmatrix function

"If the default format is 4 decimal places it should have shown 2.1342. But it doesn't."
In science and mathematics stating that a value is shown to X significant figures or decimal places means that the value is rounded to the specified digit/order (not truncated as suggest) as this reduces the relative error. MATLAB correctly displays 2.134282 with four digits after the decimal point:
format short
2.134282
ans = 2.1343
For example, the value 1.000099999 shown with four figures after the decimal point will be 1.0001:
1.000099999
ans = 1.0001
MATLAB is displaying the values correctly.
