Hi,

When trying to run the example of the main page, t-SNE returns an error:

java.lang.NumberFormatException: For input string: "1.0000000e+00   1.0000000e+00   1.0000000e+00   1.0000000e+00...
    at sun.misc.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:2043)
    at sun.misc.FloatingDecimal.parseDouble(FloatingDecimal.java:110)
    at java.lang.Double.parseDouble(Double.java:538)
    at com.jujutsu.utils.MatrixUtils.simpleRead2DMatrix(MatrixUtils.java:26)

Looks like your column delimiter is wrong. You might want to change

double [][] X = MatrixUtils.simpleRead2DMatrix(new File("src/main/resources/datasets/mnist2500_X.txt"), ",");

into

double [][] X = MatrixUtils.simpleRead2DMatrix(new File("src/main/resources/datasets/mnist2500_X.txt"), "   ");

Thank you,

Marc

Can you give it a look?
