I have seen the min-max normalization formula but that normalizes values between 0 and 1. How would I normalize my data between 0 and -1.4? I have both negative and positive values in my data matrix.

E.g., using simple linear scaling based on the range of the current data:

data = your matrix
actual_min = min(data(:));
actual_max = max(data(:));
desired_min = -1.4;
desired_max =  0.0;
result = (data - actual_min)*((desired_max - desired_min)/(actual_max - actual_min)) + desired_min;
