Write a function matavem that will receive a variablesized m

Write a function (matave.m) that will receive a variable-sized matrix as an input argument, and calculate and return the overall average of all numbers in the matrix. Use loops, not built-in functions, to calculate the average.

Solution

function matave
C=input(\'How many columns are there in P? \');
R=input(\'How many rows are there in P? \');
P=zeros(R:C);
co=1;
ro=1;
sum=0;
a=1;
while a<=R+C;
P(a)=input(\'Enter value \');
sum=sum+a;
a=a+1;
end
sum/(R+C)
P
