MATLAB: How to normalize data between specific range

Question

Hi

I have triangle signal starting from different negative values go to positive values and comeback to negative values. I want them to normalize between 0 and 1 so that there starting values will be same Itried to use this formula.

" normalized_data = data-min(data)/max(data)-min(data)"

by using above values I can align maximum values and ending points but I want to allign its starting point and its maximum point. Can any one help me what should I do.

Regrads,

To normalize data to [0 1], you need to add ( ) correctly, like:

normalized_data = (data-min(data))/(max(data)-min(data));

Another (and more easy) way is to use rescale function.

normalized_data = rescale(data);
