At least one END is missing: the statement may begin here.

for p=1:size(case_matrix,1)
    if case_matrix(p,1)==1
    scatter(case_matrix(p,4),case_matrix(p,5),'s','r');
    hold on;

See https://www.mathworks.com/help/matlab/ref/if.html (to better understand about if statements), when an if condition is used it needs to have an end

    elseif case_matrix(p,1)==4

Copy and paste this code into the MATLAB Editor. Select all that text, right-click, and select the "Smart Indent" menu option. This will line up each end keyword with the other keyword whose block it completes. Ideally, if there is a for, if, while, etc. starting in the first column of the first line, the final end on the last line should also start in the first column. For your code, it doesn't.

Looking at the code pattern I agree with KALYAN ACHARJYA's answer that your last case probably should start with elseif instead of if. When I make that change and smart indent the code, now the final end lines up with the for.

for p=1:size(case_matrix,1)
    if case_matrix(p,1)==1
    scatter(case_matrix(p,4),case_matrix(p,5),'s','r');
    hold on;
    elseif case_matrix(p,1)==2
    scatter(case_matrix(p,4),case_matrix(p,5),'o','b');
    hold on;
    elseif case_matrix(p,1)==3
    scatter(case_matrix(p,4),case_matrix(p,5),'m','*'); 
    hold on;
    elseif case_matrix(p,1)==4
    scatter(case_matrix(p,4),case_matrix(p,5),'x','g '); 
    hold on;
    else 
        disp('No Condition is Satisfied');
    end
end
