How do you show max value in Matlab plot?

How do you show max value in Matlab plot?

All you need to do is use the max() function. The max() function will return both the maximum value, and the index position of the value. You can use the index to extract the corresponding a1. Hope it helps!

How do you find the maximum value of a 3d plot in Matlab?

Direct link to this comment Idx = find((Z(:) == max(Z(:)))); [ZmaxRow,ZmaxCol] = ind2sub(size(Z), Idx); That will return all the values that equal the maximum, and their coordinates. Normally ‘maximum’ implies only one, but if you have several that could equal the maximum, this change will return all of them.

How do I make my plot points bigger in Matlab?

Direct link to this answer

1. You can change the marker size for a line plot by setting the “MarkerSize” property, either as a name-value pair or by accessing the “Line” object.
2. Name-value pair:
3. If you set this property as a name-value pair with the “plot” function, you must set it after all the x,y pairs.

How do you find the values of a graph in Matlab?

You can get the data from a plot by accessing the XData and YData properties from each Line object in the axes.

1. Make the figure containing the plot the current figure.
2. Call the gca command to get the current axes within that figure.
3. Get the coordinates from the XData and YData properties of the Line object.

How do you find the maximum value of a plot?

Direct link to this answer

1. maxF = max(F); % Find max value over all elements.
2. indexOfFirstMax = find(F == maxF, 1, ‘first’); % Get first element that is the max.
3. % Get the x and y values at that index.
4. maxY = F(indexOfFirstMax);
5. maxX = x(indexOfFirstMax);

How do you find the maximum value on a graph?

If you have the graph, or can draw the graph, the maximum is just the y value at the vertex of the graph. If you are unable to draw a graph, there are formulas you can use to find the maximum. If you are given the formula y = ax2 + bx + c, then you can find the maximum value using the formula max = c – (b2 / 4a).

How do you find the maximum value of a function on a graph?

Is Matlab local min?

TF = islocalmin( A ) returns a logical array whose elements are 1 ( true ) when a local minimum is detected in the corresponding element of an array, table, or timetable. TF = islocalmin( A , dim ) specifies the dimension of A to operate along. For example, islocalmin(A,2) finds local minima of each row of a matrix A .

How do you increase the size of a scatter plot?

1. Increase the size of all points. To increase the size of scatter points, a solution is to use the option “s” from the function scatter(), example.
2. Points with different size. To plot points with different size, a solution is to provide a list of size (or an array) to “s”.
3. Combining several scatter plots.

How do you plot a thick line in Matlab?

Direct link to this answer

1. To plot two lines with different line widths, you can use either of these approaches.
2. Return the two “Line” objects as an output argument from the “plot” function and then set the “LineWidth” property for each.
3. Use the “hold on” command to plot the two lines separately.

How do you plot in Matlab?

MATLAB – Plotting

1. Define x, by specifying the range of values for the variable x, for which the function is to be plotted.
2. Define the function, y = f(x)
3. Call the plot command, as plot(x, y)

How to get maximum value from any plot in MATLAB?

So basically If you want to plot anything, of course you need to have the data set. In order to find the maximum value, you need to employ some MATLAB functions (max and find). This will imply the peak value of your velocity profile. So far you just know the max value.

How to find the max velocity in MATLAB?

In order to find the maximum value, you need to employ some MATLAB functions (max and find). MaxVelocity = max(Y) This will imply the peak value of your velocity profile. So far you just know the max value.

What is Max ( a ) in MATLAB Max MathWorks?

If A is a matrix, then max (A) is a row vector containing the maximum value of each column. If A is a multidimensional array, then max (A) operates along the first array dimension whose size does not equal 1, treating the elements as vectors.

How to find the maximum value of a column in Excel?

M = max (A, [],dim) returns the maximum element along dimension dim. For example, if A is a matrix, then max (A, [],2) is a column vector containing the maximum value of each row. M = max (A, [],nanflag) specifies whether to include or omit NaN values in the calculation.
