How do you extract certain rows from one matrix thats first column has specific values and create a new matrix containing those rows?

I have a 126120,5 matrix. The first column has values of time. I want to create a new matrix that consists only of the rows that have time increments of 0.01 seconds from the original matrix (0.00s, 0.01s, 0.02s, 0.03s...). How can I go about doing so?

For example: M =

[0.00023 1 2 3 4 5]

[0.007 1 2 3 4 5]

[0.01 1 2 3 4 5]

[0.0127 1 2 3 4 5]

[0.02 1 2 3 4 5]

[0.0245 1 2 3 4 5]

[0.03 1 2 3 4 5]

Mnew =

[0.01 1 2 3 4 5]

[0.02 1 2 3 4 5]

[0.03 1 2 3 4 5]

I know of the command Mnew = M(M(:,1)==0.01,:);

but that is only one row and I don't want to have to do that over and over for each time. Any help would be much appreciated, Thank You!

You can use the function "mod"

M =[0.00023 1 2 3 4 5;
0.007 1 2 3 4 5;
0.01 1 2 3 4 5;
0.0127 1 2 3 4 5
0.02 1 2 3 4 5
0.0245 1 2 3 4 5
0.03 1 2 3 4 5];
Mnew=M(mod(M(:,1),0.01)==0,:);
