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)

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

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

plot(m,y,'.')

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.
