hi i want to display a zero matrix (10x10)
then i want to ask the user to select a specific row and column and then whatever the user selects will turn into 1.
example:
1 2 3 4 5 6 %where 1-6 are columns and A is the name of row
A 0 0 0 0 0 0
user will select: A,4
then the above will change into the following:
1 2 3 4 5 6
A 0 0 0 1 0 0
so that when the user enters again, this will be stored
for example second time user enters will look like this:
user will select: A,2
then the above will change into the following:
1 2 3 4 5 6
A 0 1 0 1 0 0

How are you getting this data from the user? A gui? Using input()?
What are the variable names that store the 10x10 sparse matrix, the column numbers and row letters?
Are your 1s and 0s double or logical?

Let the zero matrix be A and the row number is assigned to a variable x. Then the following piece of code can help you convert the entire row into ones:
A(x, :) = 1;
