I need to repeat the command for 10 lines so that the array is 10x60001
The code is
dt = dx1./v;
tempo = [0:dt(:,1):(length(road_x1)-1)*dt(:,1)];
"dt" is an 1x10 array with different values on each column
"tempo" is resulting in a 1x60001 array getting only the first value from dt, I need it to get the values from all the colunms resulting in a 10x60001 array, I tryed tempo = 0:dt:(length(road_x1)-1)*dt but it didn't work either.
sorry if i wasn't clear, my english is a bit rusty.

dt = dx1./v; % let dt be 10x1 array
m = length(dt) ;
n = 60001 ;
temp0 = zeros(m,n) ;
for i = 1:n
tempo(:,i) = 0:dt(i):(length(road_x1)-1)*dt(i) ; % If this results into 60001
end
In the above the RHS step should result into 1x60001 array. IF not
dt = dx1./v; % let dt be 10x1 array
m = length(dt) ;
n = 60001 ;
temp0 = cell(m,1) ;
for i = 1:n
tempo{i} = 0:dt(i):(length(road_x1)-1)*dt(i) ;
end
If your target is to get only 10x60001 array.
dt = dx1./v; % let dt be 10x1 array
m = length(dt) ;
n = 60001 ;
temp0 = zeros(m,n) ;
for i = 1:n
tempo(:,i) = linspace(0,(length(road_x1)-1),n) ; % This results into 60001
end

Trying again to code it to another sample, it's resultin in a error
Index exceeds the number of array elements. Index must not exceed 10.
Error in ESTATISTICAS_DESCRITIVAS (line 51)
tempo(:,j) = 0:dt(j):(length(road_x1)-1)*dt(j) ;
the code that I'm using right now is
dt = transpose(dx1./v); %making it a 10x1 array
m = length(dt);
n = length(verticalperf1); %verticalperf1 is na vector 1x60001, I used this vector just because sometimes the length may change and it makes the code run by the size of the verticalperf1
temp0 = zeros(m,n) ;
for j = 1:n
tempo(:,j) = 0:dt(j):(length(road_x1)-1)*dt(j) ;
end
the code results in a array (60001x10) called "tempo", its completely okay, the vallues are good and acurate, it works but the error is not allowing me to proceed, theres any way that I can solve it or just skip this error??
