Row_Echelon_calc

Here is what the calculator can do/ help sheet:

---

STEPS

• Run the code (and hope nothing breaks) All input should be done in the console.
• Input the row and col number when asked (it should always be row < row + 1=col ie 3 rows, 4 col or 4 rows and 5 col)
• Input each digit reading left to right, top to bottom. You can input negative numbers but not fractions. Please try to convert your fraction to a decimal
• After it should print out what your matrix looks like, double-check this to what you want. If not, re-run the code.
• Use the following command on your matrix! If you want to automatically put it into row echelon form it, just input “solve()”.

NOTE: All a and b are read in the standard way (Ie row 1 is row 1. You would set a = 1 if you want to look at row 1, unlike the standard python where you would us 0 to represent the 1st row. )

AUTO

AUTOMATICALLY CONVERT TO ROW ECHELON FORM: solve()

• Converts the current matrix to row echelon form automatically (steps will be recorded)

CONVERT ALL TO A FRACTION: convert_all()

• Converts the current matrix into fractions

CONVERT TO A FRACTION: convert_fraction(a,b)

• Where a and b are row and col numbers. Converts the float into a fraction.
  NOTE: a and b can't be negative in this function

MANUAL

SWAP: swap (a,b)

• Where a and b are the row numbers. A row and b row are swapped and set as each other. NOTE: a and b can't be negative in this function

ADD: add (a,b,k)

• Where a and b are the row number and k is a constant. The sum of a and k and lots of b is then set as the new a. NOTE: a and b can't be negative in this function K is set to 1 by default

TAKE: take(a,b,k)

• Where a, and b are the row number and k is a constant. K lots of b is taken away from a and then is set as the new a. NOTE: a and b can't be negative in this function, k can be. k is set to 1 by default.

MULTI: multi(a,k)

• Where a is the row and k is a constant. A is multiplied by k, which can be negative, and is set to the new a.
