Graph not showing plots

im trying to plot a graph but nothing is showing up. Not sure if its due to the for loop or not as i have tried to put values into an array but it shows an error saying matrix dimensions must agree. Any help and explanation would be appreciated.

clear;
hold on
grid on
g=9.8;
for m=60:70

y=(14*35)/(m.*g);

end

plot(m,y)

clear;

g=9.8;
m=60:70

m = 1×11

60 61 62 63 64 65 66 67 68 69 70

y=(14*35)./(m.*g);
plot(m,y)
grid on

ah i see, completely forgot to add the "." to the numerator in the function, thank you

If you want to use loop, you need to use a marker to show up the plot.

clear;
hold on
grid on
g=9.8;
for m=60:70

y=(14*35)/(m.*g);
plot(m,y,'.')
end

The loop is not necessary. However if you choose to use it, the variables must be subscripted in order to save them to vectors —

% clear;
figure
hold on
grid on
g=9.8;
for m=60:70

    mv (m-59) = m;
    y(m-59)=(14*35)/(m.*g);

end

plot(mv,y)

% clear;
figure
hold on
grid on
g=9.8;
m=60:70;

y=(14*35)./(m.*g);

plot(m,y)

Without the loop, using element-wise division (./) instead of (/) is necessary.
