I need to exporst data from a txt. file in to mathlab. The numbers in txt. file are all ready in a matrix formation and i just need to read them in the right way. Note that the numbers are some what large. The other problem that i have is that some numbers are displaying like 5,38470670569894e-006 and i don 't know how to read the properly in matrix. The whole matrx in txt. looks like this:

you can use the readmatrix function, remember to se the decimal seperator to a comma for you data
% 'format long' is only used to print more decimal number to the screen
% you don't need to use this in your code
format long
matrix = readmatrix( 'matrix_values.txt' ,"DecimalSeparator",",")
matrix = 23×3
