title: Subtracting minimum of row from the row
body: <p>I know that </p>
  
  <p>a - a.min(axis=0)</p>
  
  <p>will subtract the minimum of each column from every element in the column. I want to subtract the minimum in each row from every element in the row. I know that </p>
  
  <p>a.min(axis=1) </p>
  
  <p>specifies the minimum within a row, but how do I tell the subtraction to go by rows instead of columns? (How do I specify the axis of the subtraction?)</p>
  
  <p>edit: For my question, a is a 2d array in NumPy.</p>
