Previous matrix numbers in the formula and creating a new matrix

Hello,

I am given a matrix A=[1 2 3;4 5 6;7 8 9] ,I want to place numbers in this formula

g(x,y)=((A(x,y)-1)/(11))*(15);

Then get a new matrix B=[g(x,y)]

How to do it.

Thanks for the help

The arithmetic operators plus, +, minus, -, times, .*, ldivide, .\, rdivide, ./, and power, .^ operate element-wise.

x = 1:5

x = 1×5

1 2 3 4 5

y = x + 2 % Add 2 to each element of x

y = 1×5

3 4 5 6 7

z = y .* x % Multiply each element of y by the corresponding element of x

z = 1×5

3 8 15 24 35

a = z - 3 % Subtract 3 from each element of z

a = 1×5

0 5 12 21 32

b = x ./ y % Divide each element of x by the corresponding element of y

b = 1×5

0.3333 0.5000 0.6000 0.6667 0.7143

c = b .^ 2 % Raise each element of b to the power of 2

c = 1×5

0.1111 0.2500 0.3600 0.4444 0.5102

Use these operators to perform calculations on all elements of your matrix at once.

Thanks for the answer :)

I need everyone is numbered according to their location a loop over a matrix.

for example A(1,1)=1 is to place numbers in this formula , how to do it

[Torsten]

B = (A-1)*15/11
